The sister of Alfred Olango has filed a claim against the city of El Cajon, saying the officer who fatally shot her brother last month was negligent.

Attorney Dan Gilleon, who is representing Lucy Olango, said in the claim that Officer Richard Gonsalves had ignored his training when he “aggressively confronted” Olango — despite being told by dispatchers that the man may be mentally ill.

The claim also asserts Gonsalves should have used less-than-lethal force or de-escalated the situation until a Psychiatric Emergency Response Team arrived. The team of mental health professionals is specially trained to assist officers dealing with people who are experiencing a mental health crisis.

“The lawsuit is demanding that officers follow the rules so the rest of us can have faith that we can call 911 and a loved one won’t get shot and killed,” Gilleon said Thursday.
