The Metropolitan Police Department has arrested 18-year-old Jovante Hall in connection to a fatal stabbing yesterday at the Deanwood Metro station.

Hall, of Northeast, was arrested at 7:55 p.m. yesterday. He has been charged with second degree murder while armed.

The incident took place shortly before 11 a.m. The victim, who police have identified as 15-year-old John Rufus Evans III of Northeast, was unconscious when he was transported to a local hospital, where he succumbed to his injuries.

Evans’ mother, Terogie Wells, told NBC4 that she moved her son from D.C. to Richmond to get him away from their neighborhood in Northeast. Evans was in the District yesterday for a court appearance, she said. “It’s hard for any parent to go though something like that. He just took a part of me that I can’t get back,” Wells told NBC4. “It’s too many children, black kids, losing their lives for dumb stuff, and they really need to wake up and realize life is too short.”

Several hours after the attack, MPD released two photos of a suspect, saying that officers were in search of a black teenager or young adult with dreadlocks and braces.

Evans’ death comes less than two weeks after 15-year-old Davonte Washington was shot and killed on the platform of the Deanwood Metro station.

A Twitter account that tracks D.C.’s homicides notes that Ward 7’s murder rate has far outpaced last year.
