Peter Manfredonia, the University of Connecticut student suspected of homicides in Willington and Derby, is also suspected of abducting someone a Derby home where one of his acquaintances was found dead, according to state police.
The victim of the abduction was found in New Jersey and the search continues for Manfredonia.
Connecticut State Police are searching for the 23-year-old, who is suspected in homicides in Willington and Derby and considered armed and dangerous, and the search for him has extended into New Jersey and Pennsylvania.
Manfredonia is suspected in homicides in Willington and Derby, a home invasion in Willington and an abduction from Derby, according to police.
They said he stole the vehicle belonging to the victim of the Willington home invasion and drove to Derby, where police found the stolen vehicle abandoned in the area of Osborndale State Park.
Acquaintance Found Dead in Derby
During the search for him, police checked a home on Roosevelt Drive in Derby after learning of an acquaintance of Manfredonia and they found 23-year-old Nicholas Eisele dead.
It's not clear how the two men knew each other.
State police said it appears Manfredonia is responsible for the man's death.
The office of the chief medical examiner will conduct an autopsy and determine the cause and manner of Eisele’s death.
State police said Manfredonia is suspected.
Person Abducted From Derby Home
At the scene in Derby, State Police determined that another person might have been in the house on Roosevelt Drive and they were trying to find the person and were drafting a Silver Alert when authorities in Patterson, New Jersey notified them that they had found the person.
The person was not injured and was brought back to Connecticut and identified the captor as Peter Manfredonia, state police said.
State Police are in contact with the FBI in Pennsylvania, who are actively searching for the suspect.
Vehicle Found in New Jersey
State police said a 2016 black Volkswagen Jetta with Connecticut registration AU 78524 was taken from the scene in Derby and it was found in New Jersey, near the Pennsylvania border.
New Jersey State Police said the vehicle was found on Interstate 80 in Knowlton Township, Warren County.
Troopers said there is a bumper sticker on the driver's side of the vehicle that says "Sandy Hook Tribute Victim #26."
Suspect Seen in Pennsylvania
Manfredonia was last seen Sunday in East Stroudsburg, Pennsylvania, which is in the Poconos.
Suspect Studied at UConn
He is a senior at the University of Connecticut, where he studies in the joint School of Engineering/School of Business Management and Engineering for Management program, UConn spokesperson Stephanie Reitz said.
He first enrolled at UConn in fall 2015 and he was not living on the UConn campus at the time of the incident in Willington or during recent semesters, Reitz said.
The university said it is in contact with Connecticut State Police and they are providing assistance and information that may assist with their investigation.
Connecticut State Police said they are investigating all of the various possible leads and they are “working aggressively to bring this individual to justice."
It's unclear if Manfredonia is alone.
