WHITMAN (CBS) – A man wanted for killing his estranged wife in Marshfield was captured in Whitman. Allen Warner had been on the run since Monday evening and was the focus of a regional manhunt.

Warner was arrested in a stolen truck after a hit & run at a Whitman Dunkin’ Donuts Tuesday afternoon. Employees at the Dunkin’ Donuts say Warner came barreling down their drive thru the wrong way, crashing into some flowerpots.

“It was very scary I had no idea that it was him,” said employee Hailey Holmes. “He was laughing about it he thought it was funny, he thought it was funny that he was just going through here and he saw us and thought nothing of it, he didn’t think he was going to get caught.”

Warner was arrested by Whitman Police in a stolen T&K Asphalt flatbed truck at about 12:30 p.m.

Police said Warner was chasing Shana Warner in a car just before 6 p.m. Monday when she called 911 for help. She was later found shot in her car off Route 3A in Marshfield. She was rushed to South Shore Hospital where she died. She was 48 years old.

Warner, 47, of Rockland, ran off into the woods according to witnesses, and an active shooter alert was issued. Part of Marshfield was put into lockdown for several hours as residents were told to stay in their homes and lock their doors during the manhunt.

At a news conference Tuesday, Plymouth County District Attorney Tim Cruz said Warner was considered to be “armed and dangerous” and authorities pleaded with him to turn himself in.

Police believe Warner came to Marshfield several days ago to confront his wife. Marshfield Police Chief Phil Tavares told reporters Tuesday that Warner was well-known to them and had “numerous interactions” with local police over the years.

“He had been skulking around the area days before this in attempts to locate her, we believe,” Tavares said. Someone called Marshfield Police five days ago to report a suspicious person on School Street who was later identified as Warner. “At the time he was wearing a camouflage rain jacket and he stated he was out collecting cans. There was no criminal activity involved at that point,” the chief said.

According to court papers, Shana Warner had filed for divorce twice and she was in the process of filing a third time. A hearing had been set for January. The first time she filed was, according to documents, because “the defendant was physically and verbally abusive due to his drug use behavior.”

Shana Warner’s father told WBZ-TV she did landscaping with him and was going to marry a new boyfriend next year. “She was beautiful, she was beautiful” he told WBZ’s Louisa Moller.

“This is just another example of a despicable, cowardly act of domestic violence. It won’t be tolerated,” Chief Tavares told reporters Tuesday.
