The fatal police shooting of a 15-year-old boy at his home in Haymarket "appears to be justified," said Prince William County Commonwealth's Attorney Paul Ebert.

He said he would make an official determination Tuesday morning.

The boy was shot and killed Friday after police received a 911 call from the home that the boy had a bomb strapped to him and was holding his mother hostage with a knife, according to sources.

Police say the boy came out of his house brandishing a crowbar and approached police in a threatening manner. Police say the boy did not obey any commands to put down the crowbar, which prompted the officer to fire. The boy also apparently injured a family member with the crowbar prior to calling 911.

The shooting happened around 10:45 a.m. in the 6800 block of Hartzell Hill Ln in Haymarket, Va.

Police say officers made several commands asking the teen to drop the crowbar. The teen refused and at some point, one of the officers fired their weapon, hitting the teen in the upper body.

According to police, the teen was pronounced dead at the scene. The identity of the victim has not been released at this time.

Neighbors told WUSA9's Mike Valerio that the victim was a student at Battlefield High School, but school officials have not confirmed that. They say grief counselors were helping students cope a different school, but would not way which school.

Police have not yet released the teen's name nor the name of the officer who fired.

No officers were injured.

The investigation continues.
