Allegheny County Police arrested and charged Rosenberg in February for allegedly shooting 28-year-old Jeremy Dentel in the head inside the victim’s Baldwin home. Police say the two met on a dating app.

Allegheny County Police say their investigation into Rosenberg led him to be implicated in the disappearance of 22-year-old Christian Moore-Rouse who was reported missing on Christmas, last seen alive just a few days before.

On March 3, the body of Moore-Rouse was found near Rosenberg’s family home in Fox Chapel. The medical examiner ruled his cause of death a shotgun wound to the head and the manner of death a homicide.

A witness told police that Rosenberg said he shot Moore-Rouse in the head, and then dragged his body into the woods.

Moore-Rouse’s mother has told KDKA her son knew Rosenberg.

Rosenberg’s defense attorney said the new charges did not come as a surprise.

“At the time we were last in court with him, the issue was raised by the district attorney’s office. We have not been advised as to what the reason is for today or now. They have no emergent situation,” said Rosenberg’s attorney Wendy Williams.

In connection with Moore-Rouse’s death, Rosenberg is now facing charges of criminal homicide, robbery, abuse of corpse, tampering with evidence and firearms violations. In connection with Dentel’s death, he was already charges of facing criminal homicide, robbery, tampering with evidence and firearms violations.
