CYPRESS, Tex. -- (KIAH) -- The Harris County Pct. 4 Sheriff's Office is investigating an apparent murder-suicide after the killer allegedly used an old garage door code to break into a former lovers house, according to investigators.

Officers responded to the 14000 block of Country Road Lane after reports of a disturbance around 3:15 a.m. Investigators said the suspect was beating on the garage door of a home in the Cypress Mills Park subdivision.

Neighbor reported hearing gunshots when officers arrived. Moments later, officers found two men fatally shot and an injured woman.

"Old boyfriend broke in to the house, killed the new boyfriend, shot the former girlfriend, then shot himself," a detective said.

Investigators said the suspect was a former resident of the house. When the woman and her new boyfriend didn't responded to his knocking, the armed suspect reportedly let himself in.

"Apparently, they've been separated for a couple years. But [the victims] didn't change the code on the garage," deputies said.
