Threats of Violence Investigation – Sept. 24, at 10:12 a.m., Prince William County Police Officers responded to Park Valley Church located at 4500 Waverly Farm Drive in Haymarket to investigate a possible threat of violence.

The investigation revealed Fairfax County police contacted Prince William County police after their agency received information from police in Anne Arundel County, Maryland regarding a citizen residing in Laurel who reported recent suspicious and concerning online postings on Instagram from an individual later identified as the accused.

In the postings, vague threats of violence were made, some of which included images of a location later determined to be Park Valley Church in Haymarket (Prince William County).

Through the swift investigation led by Anne Arundel police, their officers were able to determine a potential residence for the accused in Falls Church and immediately contacted Fairfax County police concerning the postings.

When Fairfax County police responded to the home, the accused was not located. Additional information regarding a vehicle was also obtained through the joint investigation and contact was made with Prince William County police to check the church property.

At around the same time, staff at the church were monitoring a suspicious person who was determined to be the accused who was on the premises.
