ASIRT releases details of fatal, 30-hour police standoff in southeast Calgary

Details of a 30-hour standoff that ended March 15 with police shooting the suspect have been released by the Alberta Serious Incident Response Team (ASIRT).

On Monday, the provincial police watchdog outlined the circumstances that led to the death of the 45-year-old man — identified by police sources as Patrick Kimmel — who police said had history of weapons offences.

At about 3 p.m. on March 14, the Calgary Police Service's tactical team went to a southeast Calgary residence in Penbrooke Meadows to conduct a search warrant.

"Using a loudspeaker, police identified the reason for their presence and told the occupants to leave the residence. Four individuals left the residence, but one man remained inside," reads the ASIRT release.

An armed standoff began when, according to the provincial watchdog, gunshots came from the house and hit a CPS armoured rescue vehicle at around 3:45 p.m.

ASIRT said that over the next 30 hours, police service negotiators spoke to Kimmel. RCMP also attended the scene.

According to the release, police released "incapacitating gas" into the residence, but Kimmel did not leave the house.

At 8:41 p.m. on March 15, gunshots came from the front of the residence, hitting a CPS armoured rescue vehicle and an RCMP armoured vehicle.

A gunshot then came from the back of the residence and the man came into the outer doorway, ASIRT said.

Members of the Calgary police tactical unit and RCMP emergency response team fired their weapons, striking the man.

Kimmel was found holding a shotgun. Additional loaded guns were also found in the house, the agency said.

ASIRT's investigation of the incident will examine the officers' use of force.

The police watchdog investigates when police actions lead to death or serious injury, as well as serious allegations of police misconduct.
