A man with a lengthy criminal past who showed up for work at a countertop company on Wednesday and shot five of his co-workers has been arrested, authorities said. Three of them were killed and two critically wounded.

Less than two hours later, Radee Labeeb Prince drove to a used car lot about 55 miles (90 kilometers) away in Wilmington, Delaware, and opened fire on a man with whom he had "beefs" in the past, wounding him, police said.

The shooting rampage set off a manhunt along the Interstate 95 Northeast corridor. Police cruisers were stationed in medians, and overhead highway signs displayed a description of Prince's sport utility vehicle and its Delaware license plate. The FBI assisted state and local authorities in the manhunt.

Prince was "apprehended a short time ago in Delaware by ATF and allied law enforcement agencies," the Harford County Sheriff's Office in Maryland tweeted Wednesday night.

Wilmington Police Chief Robert Tracy said Prince was arrested in Glasgow, 20 miles (32 kilometers) southwest of Wilmington, after a tip led authorities to his vehicle. Prince was spotted nearby and discarded a handgun when he saw police had recognized him. He ran about 75 feet (22 meters) before being captured. No one was hurt in the apprehension.

Authorities said it wasn't clear why Prince opened fire with a handgun on his colleagues.

The sheriff's office said Wednesday night on its Facebook page that the people who died were Bayarsaikhan Tudev, 53, of Virginia; Jose Hidalgo Romero, 34, of Aberdeen, Maryland, and Enis Mrvoljak, 48, of Dundalk, Maryland.

Prince is a felon with 42 arrests in Delaware. Court records showed he had been fired from a Maryland job earlier this year after allegedly punching a co-worker and threatening other employees. He also faced charges of being a felon in possession of a gun, was habitually late paying his rent, was repeatedly cited for traffic violations and was ordered to undergo drug and alcohol counseling in recent years.

The rampage began Wednesday about 9 a.m. at the Emmorton Business Park in Edgewood, Harford County, Maryland, Sheriff Jeffrey Gahler said. Deputies arrived in four minutes but Prince had already fled.

Kevin Doyle of Thornhill Properties said he was getting tools from his truck when he heard screaming and saw three men running from the office park. The men told him someone was shooting and he asked if they had called 911. They said no, even though, Doyle said, they had phones in their hands.

"I think they were just so scared, they didn't (call 911). They had a look of terror," he said.

The victims and the suspect worked for Advanced Granite Solutions, which designs and installs countertops, the company owner told The Associated Press. Prince has been an employee for four months, working as a machine operator, owner Barak Caba told AP in a brief telephone interview. Caba was shaken and would not provide additional details.

The second shooting took place at the 28th Street Auto Sales and Service shop in Wilmington, Delaware. The police chief wouldn't elaborate the history the victim and Prince had, other than to say: "This individual knew the people he wanted to shoot."

The victim was shot in the vicinity of his head and once in the body but was expected to survive.

Police followed Prince briefly, but they lost him and haven't seen or heard from him since, the chief said. On Wednesday night, police in Delaware said Prince's car had been found unoccupied, a spokeswoman said.

Prince was fired from JPS Marble and Granite earlier this year and scared his previous employer so badly that he tried to get a restraining order in February.

At one point, Prince's former boss Philip Siason said: "He came to see me, cursed and yelled at me about unemployment benefits. I felt very threatened because he is a big guy and very aggressive on me."

A Harford County District Court judge denied the order, saying the case didn't meet the required burden of proof.

Investigators were treating the shooting as a case of workplace violence and didn't see ties to terrorism, said Dave Fitz, a spokesman for the Baltimore FBI field office.

Since November 2014, Prince has rented a three-bedroom town house in Elkton — about 35 miles (56 kilometers) from the office complex — with his girlfriend, according to a Maryland property manager.

Prince often paid his rent late, but was always polite and cooperative, said Heather Todd of Homes for Rent. The company filed eight petitions for nonpayment against the couple, but they always ended up paying and the company never had to schedule an eviction.

Prince faced several gun charges in March 2015 in Cecil County, including being a felon in possession of a firearm and carrying a handgun in vehicle. However, the charges were dropped about three months later. It's not clear why.

Wilmington, Delaware, police said Prince had 15 felony convictions there. In King County, Washington, in 2014, he was cited for leaving the scene of an accident and driving with a suspended license, according to Komonews.com.

Court records also showed that he was required to undergo drug and alcoholism counseling at the time.

Prince racked up four traffic citations in King County in 2012 and 2013, mostly for speeding.
