HOUSTON – The Houston Police Department released dramatic surveillance video of three suspects still wanted in a fatal shooting and carjacking on the south side.

The gunfire rang out in the 6800 block of London at about 1:50 p.m. Monday.

Police described the suspects as black males between 18 to 25 years of age. Video shows the four men getting out of a blue Mazda car and then running toward Cullen where they carjacked a woman and her 11-month-old niece at gunpoint.

The video shows one suspect with a rifle firing multiple shots across the street back toward the Mazda, hitting two victims. Neither the woman nor the child in the van was harmed, however.
