D.C. police have released a surveillance video that shows a person who they are seeking in connection to the fatal shooting of a 68-year-old woman.

Vivian Marrow was caught in a gunfight in broad daylight on Martin Luther King Jr. Day. Marrow had been rolling in her wheelchair near her Southeast apartment building that morning, according to The Washington Post. Neighbors say she was either headed to the grocery store or going out for a smoke.

But around 10:16 a.m., Metropolitan Police Department officers were flagged down in reference to a shooting, according to an MPD release. Upon arrival on the 2400 block of Elvans Road, they found Marrow, along with an adult male, suffering from gunshot wounds.

Officials took both victims to local hospitals. Marrow was pronounced dead. The man was admitted in stable condition.

The video shows a gunman chasing another person, as they both run past Marrow on the sidewalk.

Marrow had three children, and she was the grandmother of 11. In the community, she was known as “Miss Vivian” and “the candy lady,” neighbors told The Post. She was always optimistic despite the neighborhood’s history of crime. She’d been in the wheelchair since she was hit by a car about a decade ago.

Mayor Muriel Bowser said in a statement that D.C. lost another resident due to “senseless gun violence.” The person or people responsible for killing Marrow “must be brought to justice,” she continued.

The suspect is described as a black male, slim build, and “appears to be left handed,” according to police.

Interim D.C. Police Chief Newsham said at a press conference that the slightest bit of information about a suspect “sometimes brings closure to a case like this.”
