When does Rigor mortis begin?

Rigor mortis refers to the stiffening of the muscles after death due to biochemical processes that occur as the body’s cells begin to break down. This process typically begins a few hours after death, generally starting within 2 to 6 hours and peaking around 12 to 24 hours postmortem. The onset of rigor mortis is influenced by several factors, including temperature and the individual's physical condition at the time of death.

Understanding that rigor mortis does not begin immediately after death is crucial, as its timing can provide important information in forensic investigations. As such, recognizing the correct timeframe is vital for professionals in law enforcement and forensic science.
