The man suspected of killing a San Antonio police officer apologized to the officer's family late Monday night.
Otis McKane, 31, was charged with killing Det. Benjamin Marconi during a traffic stop on Sunday.
As he was escorted out of the police department, he reportedly apologized to Marconi's family and said a child custody battle caused him to "lash out at somebody who didn't deserve it."
Here's McKane being escorted.
A memorial was set up outside city police headquarters Monday night in Marconi's memory.
Police: Marconi targeted for being a cop
McKane was arrested without incident, city police chief William McManus said.
Marconi was killed Sunday as he wrote a traffic ticket for another driver not involved with the shooting. McKane is accused of pulling up to Marconi's patrol car during the traffic stop, walking up to the window and shooting Marconi twice.
Lt. Gov. Dan Patrick said Marconi was targeted simply for being an officer, our partner at KABB reports.
