(KCEN) -- The FBI has joined the investigation in Houston after a police officer shot and killed a double amputee in a wheelchair over the weekend.
It happened at a group home around 1:30 a.m. on September 22.
That's where officers confronted 45-year-old Brian Claunch who was accused of threatening other people in the home.
According to police Claunch was swinging an object in a threatening manner towards them and another resident.
And when he refused to drop it, one of the officers shot him in the head.
Jodi Silva of the Houston Police Department said, "It's tight quarters in there, and he was able to corner the officer back into the corner of the room."
Claunch turned out to be holding a ballpoint pen in his hand.
He had a criminal record including possession, trespassing, auto theft and resisting arrest.
