(Updated at 7 p.m.) A T.C. Williams student was arrested at the school today (Thursday) and charged in the killing of two people on a rural Virginia Highway, NBC 4 first reported.

The Alexandria Police Department confirmed to ALXnow that its officers were on scene at the high school for the arrest of a T.C. student. The case is being investigated by Virginia State Police, an APD spokesman said.

State police released the following press release about the arrest late Thursday afternoon.

An 18-year-old Alexandria male has been arrested and charged in Saturday’s double homicide in Halifax County. On Thursday (Feb. 13, 2020) morning, the Virginia State Police Bureau of Criminal Investigation’s Appomattox Field Office took Mohamed A. Aly into custody without incident in Alexandria, Va. Aly has been charged with two counts of first degree murder and two counts of use of a firearm in the commission of a felony. Aly will be held at the Blue Ridge Regional Jail in Halifax, Va.

A silver 2009 Nissan Maxima was located in the median with Ntombo Joel Bianda, 21, of Alexandria, Va., and Ayanna Munne Maertens Griffin, 19, of Germantown, Md., found deceased and lying in the grass nearby. Both had suffered gunshot wounds. “State police personnel have been working around the clock pursuing multiple leads related to this homicide investigation,” said Capt. David O.

A student at T.C. Williams tells ALXnow that the suspect, Mohamed Aly, “was telling all his friends” about the slaying. That account could not be immediately confirmed by police.

Aly was a popular student and a player on the varsity football team, and a few of his T.C. classmates expressed support for him on Snapchat Thursday night.

Via Twitter, T.C.’s athletic director discouraged players from speaking to members of the media.
