Carlton Coltrane: Police search for suspects in fatal Southeast 7-Eleven assault

WASHINGTON (WJLA) - Metropolitan police continue to search for two men who they believe are connected to an aggravated assault at a Southeast 7-Eleven that lead to the death of a D.C. man.

This surveillance video is the key to breaking a case that has left a family utterly heart broken.

Sixty-year-old Carlton Coltrane lived near Barracks Row and was often seeing walking around the neighborhood. Last Tuesday in the early morning hours, he went to the 7-Eleven on 8th Street just blocks from his home.

In the video, you can see him being beaten by a cane. The two men on either side are the men police say robbed and beat him. The punches they delivered ultimately caused a fatal brain injury, and Coltrane was pronounced dead three days later on May 9.

What is more, the attack began while Coltrane was still inside the store, and it ended, according to police, on the sidewalk outside of the store -- which is located right in the middle of the busy neighborhood popular for its restaurants and bars.

Coltrane was able to share what happened with family members before he passed. And they said he told them that the store clerk did nothing to help him.

The video of the attackers is clear, which isn't always the case. Coltrane's family is grieving, but hopes it will help police catch the men before they hurt anyone else.

The medical examiner has ruled Coltrane's death a homicide and listed the cause of death as blunt force trauma.

The Metropolitan Police Department currently offers a reward of up to $25,000 to anyone that provides information which leads to the arrest and conviction of the person or persons wanted for any homicide committed in the District of Columbia. Anyone with information about this case is asked to call the police at (202) 727-9099.
