Strangulation and Suffocation

Recommendations

Info

Petechiae • May be occasionally observed in living people • More often a finding on dead bodies, observed at autopsy • If caused by strangulation or suffocation, associated with a near-fatal experience (c) Dean Hawley and Candace Heisler, 2012 22
•Petechia, alone, in the absence of other signs like internal injuries of the larynx or ligature marks on the neck, are not sufficient to prove strangulation as the cause of death. •The case is stronger when petechiae are accompanied by a history of stridor, dysphonia or dysphagia (c) Dean Hawley and Candace Heisler, 2012 23
