D.C. police have arrested an 18-year-old man and charged him with second-degree murder while armed in a shooting that occurred earlier this month near Gallaudet University.

Kevon Austin of Southwest was arrested on a warrant Saturday, police said in a statement. He could be arraigned Monday afternoon in D.C. Superior Court.

Police said Austin is charged with shooting Gregory Darnell Troxler, 21, of Northeast, on the afternoon of Oct. 10 in the 1100 block of 8th St. NE. Troxler was pronounced dead at the scene.

The shooting, which occurred about 3:50 p.m., drew attention because of its proximity to the university. D.C. Police Chief Cathy L. Lanier went to the scene and said a police officer heard the shots and rushed to an alley where he found the mortally wounded young man.

The location was not visible to one of the main entrances to Gallaudet, located on the other side of Florida Avenue, but some students wandered over and stood at the crime-scene tape.

Lanier said the shooting had nothing do with the university but did not elaborate. The police statement issued Saturday after the arrest also did not reveal a motive.
