Investigators say the botched car burglary that ended Carias' life was the second crime Knight committed that night.
They allege on Dec. 13, Knight and a friend approached a man parked near Hobby Airport. They said Knight coaxed the man out of his black Nissan, then tried to rob him. During that robbery, a language barrier prompted the victim to literally remove his pants, give it to Knight, and then run for his life.
Shortly after midnight on Dec. 14, police said, Knight and his friend traveled a few miles south and burglarized Carias' Camaro. The car was parked outside her boyfriend's apartment, also located near Hobby Airport. Investigators said the ensuing confrontation led to Carias being shot and killed.
"It was senseless, there was no point in it," neighbor Rudy Rios told KTRK. "Over a car?"
Investigators said they got a break on Dec. 27 when they spotted the black Nissan on the road and pulled it over for a traffic stop. Knight was allegedly behind the wheel. Investigators said that during the stop, Knight confessed to his role in Carias' murder.
"We're all mad, but they caught him and we just got to wait for the law to take care of it," Ochoa-Carias told KTRK.
