HOUSTON -

An 18-year-old was shot to death in southwest Houston during a drug deal, police said.

Officials said Hamza Raza, of Sugar Land, left his brother and friends at a convenience store in the 13100 block of Carvel Lane shortly after 12 a.m. Thursday to walk down the street to buy drugs.

Investigators said Raza met a suspect only known as Dookie. When Raza tried to make the purchase, a second suspect pulled out a pistol and ordered Raza to the ground, Houston police said. When Raza tried to flee, Dookie grabbed him, officials said. Raza was shot as he tried to get away, according to investigators.

A neighbor said he heard four or five gunshots and called 911.

"The neighbor tried to do CPR and was quickly assisted by the victim's brother who happened to be in the area as well. Regardless of how well you may live your life -- you can be the greatest student in the world -- if you start dabbling in drugs, the chances of you dying significantly just increased," said Sgt. Brian Harris with the HPD Homicide Division.

Police did not release the type of drugs found at the scene.

"Whether this was his first time or his 30th time, either purchasing or selling drugs, it ultimately cost him his life tonight," Harris said.

Investigators said the suspects were 17 or 18 years old. One was described as African-American, 5 feet 6 inches tall, very skinny with sleeve tattoos on both arms. The other suspect was African-American, 6 feet tall, 165 pounds, wearing a T-shirt with blue jeans.

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