A person of interest in the slaying of a Rostraver woman last month has been arrested on unrelated charges, according to the Westmoreland County District Attorney’s Office.

Spokesperson Melanie Jones did not release his name Wednesday. No charges have been filed in connection with the April 11 death of Jennah M. Seibert, 24, who was killed in a Lenity School Road home. Police continue to investigate, according to the DA’s office.

Jones would not say where the person of interest was arrested or the nature of the unrelated charges against him. He is the same person whose identity police sought by releasing surveillance photographs from a Monongahela convenience store.

Seibert was found dead in a bed by her fiance, according to court filings. Authorities have said Seibert was fatally shot.

A Lexus GX550 SUV belonging to the couple was stolen from the home and tracked through the vehicle’s GPS, license plate readers and traffic cameras to Monongahela, where it was recovered. Investigators requested video and photograph surveillance evidence from CFS Bank, whose system captured the SUV driving past its West Main Street location, according to a search warrant.
