Peter Manfredonia — a 2015 Newtown High School grad and University of Connecticut student wanted in a deadly crime spree — was taken into custody Wednesday night, according to authorities.

Police say two people died, a man was seriously injured, a woman was released after being kidnapped and another man was the victim of a home invasion.

The 23-year-old Manfredonia was taken into custody in Hagerstown, Maryland.

Here’s what we know and don’t know so far:

What we know:

Manfredonia was taken into custody by U.S. Marshals and Maryland’s Washington County Sheriff’s Office near the Pilot Travel Center, a truck stop on Halfway Boulevard in Hagerstown, Md.

Hagerstown police in Maryland on Wednesday (Mary 27) said the department “received information that fugitive Peter Manfredonia may be in the Hagerstown area ... We believe that Manfredonia may still be carrying a large black duffel bag and that the bag contains firearms.”

Hagerstown police said Manfredonia abandoned a stolen vehicle in the parking lot of a Sheetz gas station in Chambersburg, Pa., on Tuesday. Police said the vehicle was discovered on Wednesday.

Hagerstown police say they believe Manfredonia is still in the Hagerstown, Washington County area and urged any residents to call in sightings to 911.

Maryland State Police told Hearst Connecticut Media that the agency notified all its troopers that Manfredonia is in Maryland and wanted on various offenses and urged anyone who sees him to call 911 immediately.

Earlier in the week, Manfredonia’s last sighting had been in East Stroudsburg, Pa., after police say he ditched the stolen car he was driving and the woman he kidnapped from Derby in New Jersey late Sunday (May 24) afternoon.

The FBI has joined police agencies in Connecticut, New Jersey and Pennsylvania in the search.

Police said Manfredonia is the suspect of a Friday homicide and assault in Willington, where Theodore DeMers was killed with an edged weapon and another man was also attacked. Manfredonia was allegedly in the area to see an ex-girlfriend.

As of Sunday, police said the second victim in the Willington attack was still facing life-threatening injuries. By Tuesday, he was in stable condition. His wife says his hands were injured the most.

Manfredonia is considered to be armed and dangerous, according to police, who said he is armed with a handgun and long guns.

Police said Manfredonia held a homeowner on Turnpike Drive in Willington against his will on Sunday (May 24) morning. When he left, Manfredonia took supplies from the homeowner, including food, firearms and his truck, police said.

According to police, Manfredonia crashed the truck in Derby on Sunday (May 23), setting off a search in the area.

Police say Manfredonia then went to the home of 23-year-old Nicholas J. Eisele, a former classmate of his at Newtown High School who was living in Derby. Police found Eisele dead, but have not yet ruled it a homicide. When police arrived at Eisele’s home around 11 a.m. Sunday (May 24), Manfredonia was gone, having stolen the man’s girlfriend’s black Volkswagen Jetta with with a Connecticut license plate and a bumper sticker that paid tribute to the 26 victims of the Sandy Hook massacre.

State police said Manfredonia took Eisele’s girlfriend against her will from the Derby home before releasing her in New Jersey.

On Tuesday, Connecticut Chief Medical Examiner James Gill said DeMers died of “sharp force and chop injuries of head with sharp force injuries of torso and extremities.” Gill said Eisele’s cause of death was “gunshot wounds” to the head.

The Jetta was found in New Jersey near the Pennsylvania boarder, police said. Manfredonia was then sighted in East Stroudsburg, Pa. That was his last sighting shared by authorities until Wednesday, when they said he was in Maryland.

What we don’t know:

Did Manfredonia surrender to police, or was he taken into custody at gunpoint? Conflicting reports were circulating late Wednesday night regarding the circumstances of his capture.

What charges will he face? State police in Connecticut said whether he faces state or federal charges is still to be determined as the investigation continues.

Manfredonia’s current location. Wednesday (May 27) afternoon, Pennsylvania State Police said Manfredonia was driven to Maryland by an Uber driver, to the area of Hagerstown. Police have not said if there have been any further sightings.

Police have not said if they know what motivated the killings.

Police have said two people have died, another man was seriously wounded, one woman was kidnapped and another man was held against his will in his Willington home. It is not known if there are any other victims.

Police said they have interviewed the woman Manfredonia is accused of kidnapping. Police have not yet said why he kidnapped the woman or why he let her go in New Jersey.
