A doctor involved in treating the Boston Marathon bombing suspect who died in a gunbattle with police says he had injuries head to toe and all limbs intact when he arrived at the hospital.
Dr. David Schoenfeld (SHOW'-en-feld) says 26-year-old Tamerlan Tsarnaev (tsahr-NEYE'-ehv) was unconscious and had so many penetrating wounds that it isn't clear which ones killed him. The doctor says a medical examiner will have to determine the cause of death.
Schoenfeld says the suspect was in cardiac arrest and lost a pulse as soon as he arrived at Beth Israel Deaconess Medical Center following a shootout with police in the Boston suburb of Watertown early Friday. Doctors tried numerous treatments for about 15 minutes before pronouncing him dead.
The doctor said "we did everything we could" to try to save his life.
