HOUSTON -

Houston police are looking for clues on the one-year anniversary of a murder that left three people dead.

On April 17, 2013, two men and a woman were shot to death at 1325 Greens Parkway.

Elizabeth Mayorga, 18, and Anthony Contreras, 18, were both pronounced dead at the scene. Cesar Jose Enriquez, 36, was transported to Memorial Hermann Hospital where he later died.

Police said Enriquez did not show up to work that day, so a co-worker went to his apartment to check on him. Finding the door open, the co-worker went inside, saw blood on the walls of the bedroom and then called 911.

Officers went to the scene and found Enriquez, Contreras and Mayorga all in the bedroom. All three suffered gunshot wounds to the head. A baby girl was also in the bedroom. She was not harmed. Police said the baby was the daughter of Contreras and Mayorga.

At this time, there is no known description of the gunman. 

Anyone with information in this case is asked to call the HPD Homicide Division at 713-308-3600 or Crime Stoppers at 713-222-TIPS.
