Manassas, VA – Prince William County police have announced four additional arrests in the ongoing homicide investigation into the fatal shooting of an 18-year-old Manassas man during what investigators say was a planned robbery.

The victim, Luis Angel Chavez, 18, was shot and killed June 15 in the Bull Run Mobile Home Community near Peppertree Lane and Pebble Lane.

Detectives announced that four more suspects have been charged in the case following an ongoing investigation.

Arrested were:

• T’Kiyah Serenity French, 19, of Stafford, charged with felony murder, conspiracy to commit robbery, and use of a firearm in the commission of a felony. She is being held without bond.
• Ja Quad Dyzae Andrews Washington, 20, of Fredericksburg, charged with felony murder, robbery resulting in death, second-degree murder, use of a firearm in the commission of a felony, and conspiracy to commit murder. He is being held without bond.
• Austin Wainaina Wyman, 19, of Woodbridge, charged with felony murder, conspiracy to commit robbery, and use of a firearm in the commission of a felony. He is being held without bond.
• A 15-year-old juvenile from Manassas, charged with felony murder, conspiracy to commit robbery, and use of a firearm in the commission of a felony. He is being held at the Juvenile Detention Center.

The latest arrests follow several others already announced in the case.

On July 1, detectives arrested a 17-year-old juvenile in Manassas Park with assistance from the Bureau of Alcohol, Tobacco, Firearms and Explosives and the U.S. Marshals Task Force.

Police had previously charged Markiss Alexander Medrano and a 16-year-old juvenile in connection with the homicide.

Police said officers responded around 9:57 p.m. on June 15 to reports of gunfire near Old Centreville Road and Parkland Street.

Investigators determined Chavez had been shot in the upper body in the Bull Run Mobile Home Community. After being wounded, he attempted to flee before collapsing in the backyard of a residence on Parrish Lane, where officers found him and attempted lifesaving measures. He was pronounced dead at the scene.

Authorities also found a nearby residence on Peppertree Lane had been struck by gunfire. Detectives believe the incident was targeted and not random.

The investigation remains ongoing, and police are asking anyone with information to contact the Prince William County Police Department.
