(NEW YORK) -- A man who is suspected of killing three co-workers Wednesday in Maryland is now wanted in connection to a shooting in Delaware, law enforcement authorities said.
Radee Labeeb Prince, 37, allegedly shot five people, killing three, at the Advanced Granite Solutions office in Edgewood, Maryland.
He entered the facility around 9 a.m. and was an employee there, according to Harford County Sheriff Jeffrey Gahler. After the shooting, sheriffs said Prince fled the scene in a 2000 black GMC Acadia. The car has Delaware license plates.
"There’s an individual out there on the loose who committed one of the most heinous acts we’ve ever seen in our county," Gahler told reporters. He confirmed that Prince has a criminal history and said he remained "armed and dangerous."
Prince was also wanted in connection to a separate “shooting event” in Delaware, Gahler noted.
Police in Wilmington, Delaware, released a statement echoing Gahler, confirming they were actively searching for Prince.
Gahler said the motive of the shootings remained a mystery, but the first target was the home improvement business where Prince worked.
“We know he worked here," Gahler said. "He was scheduled to be at work today.”
He added, "We think it ties into the relationship here at work. I do believe he’s targeting for a specific reason and not general.”
Two of the Maryland shooting victims were transported to University of Maryland Medical Center and remain in serious condition, Gahler confirmed.
"Everyone shot is in serious condition," Gahler said.
The Harford County Sheriff's Office tweeted a photo of Prince, including his birth date as well as the vehicle's license plate number.

The tweet warned: "Call 911 if you see the suspect."
Prince is believed to have acted alone.
"We do not believe anybody else is connected to the shooting," Gahler said.
The Harford County Sheriff's Office is working with the FBI to investigate the shooting. An FBI official told ABC News that the agency is treating the incident as "workplace violence" and there are no indications of terrorism at this point in time.
Edgewood is about a 40-minute drive north of Baltimore, and a short distance to the second crime scene in Wilmington.
The close proximity to the crime scene was enough to cause Harford to warn the public that Prince could return quickly.
“He’s mobile," Gahler said. "He could be back here in Harford County in 10 minutes.”
