PITTSBURGH (KDKA) – Human remains have been found outside the Fox Chapel home of a man who was just arrested in February after a 28-year-old was found shot dead in Baldwin.

The remains were found on Settlers Ridge Road, near the family home of homicide suspect Adam Rosenberg.

The 21-year-old was arrested about two weeks ago for allegedly shooting and killing a man, 28-year-old Jeremy Dentel, in Baldwin. Dentel was found shot in the head inside his home.

Officials say the remains were found Tuesday morning in a wooded area off Settlers Ridge Road. They were found on public land near Rosenberg’s house. The remains weren’t buried but weren’t visible from the road.

Police interviewed Rosenberg regarding Dentel’s death and he said they met on the dating app “Find Men” and began texting.

After Dentel’s murder, officials searched Rosenberg’s home in Fox Chapel. They found Federal Cartridge 9mm Luger FC ammo in his bedroom closet. The ammo box was a 250 count with seven bullets missing. The headstamp matched that of the bullet found at Dentel’s feet.

Rosenberg was arrested on charges of criminal homicide, robbery, firearms violations and tampering with evidence.

Police say it wasn’t a tip, but rather an ongoing investigation that led them to Settlers Ridge Road.

Moore-Rouse’s mother was on scene and tells KDKA her son and Rosenburg were friends from college and that she had a feeling Rosenburg had something to do with her son’s disappearance.

Moore-Rouse was a student at Pittsburgh Science and Technology Academy before moving on to Taylor Allderdice where he graduated in 2016.

He went on to CCAC, where he last attended in the spring of 2018.

He was majoring in general studies.

Police say they’ve received questions in response to statements by Moore-Rouse’s family members, claiming investigators were told about Rosenberg’s possible involvement in Moore-Rouse’s disappearance in December.

“We understand that these are trying times for the family, but we disagree with that characterization,” Allegheny County Police Department Superintendent Coleman McDonough said in a statement.

“The Allegheny County Police Department received this case on January 6. The name Adam, without a last name, was provided to investigators in January. He was identified as an acquaintance of Mr. Moore-Rouse, as were others, but not implicated in Mr. Moore-Rouse’s disappearance.”

The Rosenbergs’ attorney Casey White says now the family is coping with today’s discovery on top of their son already facing charges.

The medical examiner has not identified the remains found on Settlers Ridge Road.
