Calgary police shot and killed a 33-year-old woman in the southeast community of Penbrooke on May 17, 2018. Police allegedly responded with a canine unit to a reported break-in at a home on the 100 block of Penbrooke Close SE a bit after 11 AM. While the tactical unit was setting up police entered a room in the basement where two people were believed to be present. One officer reportedly fired an Arwen plastic bullet gun, striking a man. Soon after the man was hit an officer shot and killed the woman. She was declared dead at the scene.
Police report that both tactical unit officers who fired their weapons were constables. One has been with the Calgary force for seven years, the other for 12 years. None of the police reports have been independently confirmed publicly. The Alberta Serious Incident Response Team (ASIRT), the institution that examines cases of police harm to civilians in the province, is investigating.
