Two people died overnight at an apartment complex on the western edge of Smithfield, but police are releasing few details.

Officers responded to Jersey Park Apartments in the 700 block of Wrenn Road, off West Main Street, after a call reporting “a suspicious circumstance,” the Smithfield Police Department said in a news release. Police did not identify the two victims.

Bullet casings were found at the scene, “but the exact cause of death remains unknown at this time,” the new release stated.

Police said they were gathering more evidence and interviewing witnesses.

Smithfield Police Investigations Lt. William Wooley told The Smithfield Times by phone that he could not release further details, including approximately what time police were called to the scene.

Police were still on scene shortly before 9 a.m. on July 18 flanking each side of the entrance to one of the apartments with white tarps as the bodies were removed from the building.

Several residents of the apartment complex who had gathered outside the apartment declined to provide details to the Times, aside from one who described the incident only as a “shooting.”

“We understand the concern and interest of the community and the media in obtaining more information about this case,” the police news release stated. “However, to protect the integrity of the investigation and maintain the privacy of the victims and their families, specific details regarding the identities of the victims and any potential suspects cannot be disclosed at this stage.”

Virginia State Police investigators are assisting in the case.

Anyone with information about the deaths is asked to contact the Smithfield Police Department, the Crime Line at 1-888-LOCK-U-UP or use the P3 Tips App. Information that leads to an arrest can earn the caller a cash reward of up to $1,500 while remaining anonymous and not having to appear in court.
