Two people were found shot dead in the driveway of a north Houston home, police said. Investigators are examining whether the shooting involved domestic violence.

Officers went to a home on Lindale near Irvington after a caller reported a drive-by shooting around 8 a.m. Police spoke with neighbors who had heard gunshots before finding the two victims.

Relatives told police that the woman had argued with an ex-boyfriend before the shooting. Investigators located the ex-boyfriend and have been speaking with him, but have not established who killed the two people. They are gathering evidence at the home and looking for surveillance video.
