HOUSTON (AP) — A 27-year-old wheelchair user who shot a relative is in custody after a five-hour standoff with Houston police at his home.

Police spokesman Victor Senties tells the Houston Chronicle (http://bit.ly/1KVJ9p8 ) the incident started late Sunday night. Officers went to the house after the suspect and a family member argued and the suspect shot his relative in the arm.

The wounded man was taken to a hospital. Senties says the injury wasn't life-threatening.

Senties says officers then heard gunshots in the home and SWAT was called, but the suspect refused to speak to negotiators.

By early Monday, the suspect surrendered.

Senites says the suspect's family told investigators he has post-traumatic stress disorder after being shot in a home invasion a couple of years ago, which resulted in him using a wheelchair.
