26-year-old Bryan Capps says he believes if police officers had responded to his father's home with knowledge of his mental illness, he could still be alive.
"I'm sorry the cop got hurt. But we ain't got a dad now. And I think it could have been handled way different," said Capps.
Capps says his father spent time in Lakeshore Mental Health Institute about six years ago after being arrested by KPD.
"They came and arrested him and that's why he went to Lakeshore and got help," said Capps. "They should have known he was mentally unstable."
Police Chief David Rausch says his officer acted professionally and properly when responding Friday night.
He says they'd already responded to two domestic calls at the home this year. But he says those experiences gave them no reason to be on special alert when responding Friday.
He says if they had more information they would have handled the call differently.
Rausch says there was a second officer on the way when the incident occurred.
He says he's listened to the audio recording of the shooting and says he was impressed by how his officer handled it.
"His calm demeanor, his attempt even while being assaulted to deescalate the situation," explained Rausch.
On Saturday evening, neighbors of Capps held a vigil in his honor.
Bryan says they family has been touched by the outpouring of support by friends they never knew his father had.
He says when his father returned home from Lakeshore years ago, he ran out of medication and then refused to go back on it
The entire family tried to juggle work and his father's care, but they became overwhelmed and felt unable to compel him to seek treatment.
Rausch says he'd like to see more discussion about options for families dealing with mental illness.
"I still think it comes down to families making sure they get help for their loves ones when they need it," said Rausch.
