10/7/2013 Strangulation Realities: What You Don’t Know Can Hurt Her KIMBERLY WYATT DEPUTY PROSECUTING ATTORNEY, KCPAO GABRIELLE CHARLTON DEPUTY PROSECUTING ATTORNEY, KCPAO TERRI STEWART RN SANE HCSATS DETECTIVE JENNIFER SAMPSON SEATTLE POLICE DEPARTMENT, DV UNIT WHITNEY HELLYER, MSW ADVOCATE KCPAO CSI vs. REALITY VS. Realities of Strangulation 1 10/7/2013 2 10/7/2013 “ He choked me” asthma.WAV What does it mean to us when the victim says he choked her? MEDICAL REALITIES 3 10/7/2013 “Choking” vs. “Strangulation” Choking Choking is an internal blockage of the airway (e.g. choking on a piece of food). Strangulation Strangulation is an external blockage of the blood vessels and/or airway. It occurs from pressure placed on the neck resulting in a reduction of blood flow to the brain also known as asphyxia. 4 10/7/2013 STRANGULATION Occurs from pressure placed upon the neck Resulting in reduction of blood flow through the brain If this persists, then oxygen delivery to the brain is impaired, and the brain cells become hypoxic (low oxygen), then anoxic (lack of oxygen), then dead This type of serious bodily injury is called ASPHYXIA, and it occurs first at the cellular level, then throughout the body Asphyxiation The rate of development of asphyxiation depends primarily on the circulation of blood through the brain To a much lesser extent it depends on the victim’s ability to breath through the airway Airway obstruction is rarely a factor in fatal strangulation assault Death may be accelerated if suffocation occurs simultaneously with the strangulation assault. Types of Strangulation Most often the blood flow through the brain is obstructed by compressing the jugular veins, while leaving the carotid arteries open. Obstruction of the carotid arteries requires a great deal of force, but if it is done, then unconsciousness and death can occur in just a few seconds 5 10/7/2013 Types of Strangulation Manual Hands around neck Ligature Use of a device (belt, cord, necklace, etc) around neck Neck Holds i.e. “choke” hold Injury Realities External signs of strangulation are absent in half of all cases Death can occur without any external marks Lack of visible injury should not mean lack of medical assessment HYOID BONE CAROTID ARTERY THYROID CARTILAGE (with fracture shown) JUGULAR VEIN TRACHEAL RINGS 6 10/7/2013 Why the victim will lose consciousness blocking of the carotid arteries depriving the brain of oxygen blocking of the jugular veins preventing deoxygenated blood from exiting the brain closing off the airway causing the victim to be unable to breathe Loss of Consciousness Unconsciousness can occur in a strangulation event within 10 to 30 seconds. Brain death will occur in 4 to 5 minutes, if strangulation persists 7 10/7/2013 Most Common Symptoms Hoarseness if the most frequent symptom Caused by crushing of the nerves/vocal cord against neck structures Temporary May Potentially Can nerve damage be reversible irreversible require surgical intervention Most Common Symptoms Scratches to the Neck Caused by the victim (she did do it to herself) An attempt to get assailants hands off neck response with goal to stay alive Primal Most Common Symptoms Memory Loss Commonly found after major trauma and may be a cause of memory loss after strangulation May not be able to record memory of the event due to the traumatic experience May mean victim had a period of unconsciousness with lack of oxygen to the brain 8 10/7/2013 Most Common Symptoms Loss of Consciousness (LOC) Result of lack of oxygen to the brain and death of brain cells Unconsciousness occurs rapidly after closure of the carotid arteries Patients reporting LOC need IMMEDIATE medical evaluation for potential stroke or clotting in the vessel A singular petechiae to the face or eye after passing out means there are petechiae in the brain which means there is permanent damage to brain blood vessels and tissue Damage can never be repaired and can be seen on autopsy even 60 years later Most Common Symptoms Urination or Defecation This is a response of the autonomic nervous system, an involuntary body response Indicates a profound loss of consciousness causing relaxation of the sphincters This is a higher degree of loss of consciousness than is seen in the operating room Indicates a near fatal assault/strangulation Physical Signs and Symptoms Primary Initial Signs Specific: Pattern injuries such as ligature abrasion or fingernail abrasion Non-Specific: Erythema, swelling, abrasions, contusions 9 10/7/2013 Secondary Physical Signs Facial congestion, cyanosis Petechiae Facial skin especially periorbital Conjunctivae of eyes, eyelids Oral mucosa Petechiae (tiny red spots) Rupturing of capillaries (causes brain cells to die) Where will you find petechiae? From point of strangulation and up – never below outside and inside Hairline Inner ear (usually only visible with magnified scope) Presence or lack of presence does not prove or disprove strangulation Eyelids, both 10 10/7/2013 Internal Brain Injuries If there is one spot of petechiae on the face or eyes, there are petechiae in the brain If there are petechiae in the brain there is cell death and brain damage Seriousness of Strangulation and Suffocation There is a continuum of responses to strangulation and suffocation Even the moment of loss of consciousness is unpredictable Many victims are rendered unconscious in seconds Death can occur within minutes or even days later 11 10/7/2013 Non-Fatal Prolonged or Delayed Medical Complications of Strangulation Assault Persistent failure of swallowing with malnutrition Persistent hoarseness of voice or aphonia Recurrent headache and persistent neck pain are common complaints, but too vague in origin to state within reasonable medical certainty that it was caused by the strangulation. Miscarriage is alleged to occur, and the physiology for the fetus would be impacted by the event, but proof of causation would be difficult. Potentially Fatal Medical Complications of Strangulation Assault Aspiration of gastric contents with pneumonitis Fracture of trachea or larynx with air leak Swelling of the glottis or larynx with airway obstruction (complicated by intoxication) Carotid artery dissection or thrombosis with stroke In one case, persistent pain on swallowing apparently caused the victim to become dehydrated in a hot residence, and death was by dehydration. Medical Treatment Document patient statement, visible injuries and physical symptoms Photograph injuries Patients with visible injuries or physical symptoms should ideally be monitored in an ED for 6 hours Patients reporting loss of consciousness should ideally be medically monitored for 24 hours Anyone reporting strangulation should advised to have someone with them in the immediate 24-48 hours post strangulation 12 10/7/2013 BUILDING YOUR CASE The Importance of First Responders Things that can change as time passes: Guilt Regret “It’s my fault” Pressure from suspect Pressure from family members Money, housing, jail, etc ….. “Did I exaggerate – was it really that bad?” “I don’t see any bruises” Ask, Ask, Ask & Document, Document, Document 1. How did he strangle you (What method was used)? 2. How long did he strangle you? 3. What did you see when he was strangling you? 4. Did you have difficulty breathing? 5. Did you lose consciousness? 6. What did he say while he was strangling you? 7. What did you think was going to happen? 8. Did you notice anything else about your body? 13 10/7/2013 Describe the Method of Strangulation One Hand Two Hands Describe the Method of Strangulation Strike Arm Methods continued….. Carotid Restraint Hold Ligature used? “Choke Hold” 14 10/7/2013 Signs & Symptoms And follow up questions… Visible Signs of Strangulation BLOOD RED EYES NECK SWELLING RED SPOTS (PETECHAIE) SCRATCHES BRUISING ROPE BURNS Scratches Vertical vs Horizontal Vertical – victim’s fingernails Instinctive effort by victim to regain ability to breath. The marks show she tried to pry whatever blocked her ability to breath away from her neck. Horizontal - Suspect 15 10/7/2013 Impression marks Crescent moon shapes = fingernails Signs of Strangulation Petechiae 16 10/7/2013 Symptoms of Strangulation VOICE CHANGES: hoarseness, change in pitch, raspy voice, partial or total loss of voice SWALLOWING CHANGES: difficult but not painful, pain when swallowing, pain to throat, and coughing or clearing of throat BREATHING CHANGES: hyperventilation, having trouble catching breath BEHAVIORAL CHANGES: memory, amnesia, agitation, anger, concentration – often dismissed as “drama” LOSS OF BODILY FUNCTION: Vomit, urinate, defecate Symptoms found to worsen with increasing # of strangulation incidents Documentation/Scene Checklist PHOTOS: don’t ask permission, just take them The victim’s body is the crime scene / evidence Don’t forget the defendant – are there defensive wounds? (E.g. bites marks, scratches on hands/arms) Take the rope, necklace, weapon, torn clothes/wet clothes (check bed, sofa, floor, etc and document) The scene tells the story Photograph Must Haves The body is a crime scene Victim and Suspect Full Mid body (establishing shot) Must show the face range Area of injury Close up of injury With and without a ruler Common Mistake: Single photo of injury without an establishing shot – Whose body does that injury belong to? 17 10/7/2013 Injuries/Medical Attention Injuries from strangulation are often not visible: Injuries from strangulation can be internal – no signs or symptoms Onset of symptoms can be delayed (e.g. internal swelling, respiratory or neurological damage) Pregnant victims – injury to fetus is always possible Symptoms can worsen if subjected to repeated strangulation incidents Call the Medics – err on the side of caution Investigation Recap Patrol Officer – most important piece of investigation (window of opportunity) 50% + have no visible injuries with or without loss of consciousness Ask the questions & document the answers Remember, a follow up visit may be necessary to document delayed signs and symptoms Collect the evidence and get a written or recorded statement Call for medical attention / Get medical release signed Hurtado – step outside the room/ambulance Statements Statements should include “Smith Affidavit” “Do you declare under penalty of perjury under the laws of the State of Washington that the statement you have made is true and correct and may be used in court?” 18 10/7/2013 Get Certified Online in 30 minutes! www.strangulationtraininginstitute.com/training.html Lethality and Law Enforcement ADVOCACY & LETHALITY 19 10/7/2013 Continuum of Violence Strangulation? Study by Glass, et all, 2008 Study examined non-fatal strangulation by an intimate partner as a risk factor for homicide Researchers compared women who had experienced physical intimate partner violence that did not include strangulation to women who had Victims of prior non fatal strangulation were found to be 7 times more likely to become a homicide victim than those who had not Victims of prior non-fatal strangulation were found to be 6 times more likely to be the victim of an attempted homicide The Chicago Women’s Health Study • Found that 24.6% of the 57 women killed by a male intimate partner in 1995 and 1996 were killed by strangulation or smothering • Of the women sampled in Chicago hospitals and clinics who reported having been a victim of intimate partner violence, 47.3% had experienced at least one incident of strangulation in the past year • Of 289 incidents of strangulation, 4.8% resulted in death • Of 4,722 incidents of violence other than strangulation, only 1% resulted in death 20 10/7/2013 The Power of Advocacy Listen for What You Can’t See • Horse voice • Headaches • Loss of voice • Memory loss • Difficulty or pain • Dizziness • • • • • swallowing Neck Pain Headache Nausea/Vomiting Difficulty breathing Loss of consciousness • Problems concentrating • Coughing • Trauma symptoms (ie. insomnia, nightmares, flashbacks, hyper vigilance) Encourage Medical Care Clients often refuse medical aid because: They don’t think their injuries are serious enough. They don’t have medical insurance. Their symptoms don’t appear until hours or days later. Assessment, education, and resource referrals can reduce barriers and make sure victims of non-fatal strangulation get the medical care that may save their lives. 21 10/7/2013 Educate, Educate, Educate (Did I mention educate?) Knowledge can improve the physical and emotional safety of our clients. Strangulation Brochure Document It App Everyone needs to know this information. Everyone. Tell them. PROSECUTION & NON-FATAL STRANGULATION After the police report… • Felony • Misdemeanor filing – city or county • No PC – not referred to prosecutor 22 10/7/2013 King County Statistics • King County PAO Stats: file 200+ A2 Strangulations per year • 2nd most common felony DV crime • Since 2007 (change in law), over 1000 • These statistics do not take into account misdemeanors charged at county and city levels or cases referred for prosecution and not filed • Safe to say, county-wide numbers are much higher as to rate of occurrence Felony Filing King County Prosecutor’s Office Filing Standard Domestic violence strangulation and suffocation cases shall normally be filed as Assault in the Second Degree when there is sufficient admissible evidence that the victim suffered a temporary, but substantial, loss or impairment of the ability to breathe. Examples of strangulation include: loss of ability to breathe, which is more than momentary; injury to the neck including bruising or injury to the voice box; petechial hemorrhage; temporary loss of a bodily function (e.g. consciousness, bowels, etc). *RCW 9A.36.021(1)(g). Misdemeanor Filing When prosecuted as misdemeanor, must treat it as one of the most serious misdemeanor cases. If you think this case should be a felony, don’t be afraid to ask us to review. Consider whether follow-up is warranted based on new info from victim, advocate, etc – does this change misdemeanor vs. felony analysis? 23 10/7/2013 Prosecution Challenges • Limited physical evidence • “He choked me and left no marks” • • • • He said/she said – no other witnesses Loss of consciousness/memory Victim minimization/recantation Lack of education/awareness surrounding strangulation • Dispelling juror misconceptions/expectations (CSI effect) How to Face the Challenges: Where to look for additional evidence 911 recordings -what did the victim say- is she coughing/ trying to clear her throat. Is she trying to catch her breathe (like the opening 911 call we heard)? Jail recordings- Did the defendant make admissions about the strangulation Children- what did the children seeFire/Medic run sheets Work with your Advocate, Detective and Medical Professionals Look for missed witnesses Why coordination matters Ashley’s story Jail calls – use as leverage Defendant sent to prison for 57 months on the A2- strangulation (based on criminal history) 24 10/7/2013 Another story V was 5 months pregnant Visible petechiae and marks on neck Limited photos Child present (D’s nephew) Medics not called – no meds Felony filed V recant Outcome: D PG to A4 Promising Practices System Coordination Co-located prosecutors Other ways to increase coordination?
