Chadwick was found dead inside his residence in the 3400 block of Sexsmith Road.

Crown Counsel told the court that Williams allegedly assaulted his roommate with a piece of wood. In opening statements to the jury, Crown stated that after Chadwick had been struck once, he fell down a flight of stairs before Williams allegedly bludgeoned him to death, leaving behind a piece of wood and a pair of glasses.

The day prior to Chadwick鈥檚 death, police had responded to two calls from people requesting wellness checks for Williams.

The police watchdog completed an investigation into the 91大黄鸭 RCMP, and whether their actions, or lack thereof, contributed to Chadwick鈥檚 death. They were subsequently cleared of wrongdoing.

Crown will be calling on responding police officers and paramedics, as well as the officers who processed the crime scene as witnesses. The doctor who performed the autopsy will also be called to testify.
