PLYMOUTH — Shana Warner dialed 911 and screamed into the phone.

Her estranged husband jumped into her SUV as she drove through Marshfield at 6 p.m. on Monday, she told the dispatcher, and she was “very hurt,” according to a police report released Wednesday.

A short time later, officers found Warner, 48, bleeding heavily from her chest and shoulder and lying on her back near a gray Toyota Scion that went off the road at the intersection of Main Street and Old Main Street Extension. Investigators concluded she had been shot, stabbed, and run over with her own vehicle.

On Wednesday, her estranged husband, Allen Warner, 47, of Rockland, appeared in Plymouth District Court, where a prosecutor said he pursued his wife Monday evening as she drove away from her father’s house in Marshfield, savagely attacked her, and then left her to die on the side of the road. She was pronounced dead at South Shore Hospital in Weymouth.

“He’s purely evil and just committed an extreme, atrocious act of domestic violence,” Marshfield Police Chief Phillip A. Tavares told reporters following Allen Warner’s arraignment. “This is just a horrible, horrible case.”


A not-guilty plea was entered on his behalf to a murder charge, though Plymouth District Attorney Timothy J. Cruz said Allen Warner may face more accusations. Judge James Sullivan ordered him held without bail and sent him to Bridgewater State Hospital, where he will be evaluated for his competency to stand trial. His next court date was scheduled for Oct. 15.

Plymouth Assistant District Attorney Jessica Elumba said investigators identified Allen Warner as the killer after speaking with friends and relatives of the estranged couple and several witnesses, some of whom saw portions of the confrontation.

“These are always terrible, tragic cases,” Cruz said. “I feel so much for the family that has to go to court and listen to these terrible facts.”


About a half-dozen mourners attended the arraignment. As Elumba described Shana Werner’s injuries, including gunshot wounds and knife cuts to the spine, face, skull, and shoulders, one man doubled over and buried his head in his lap.

Before the attack, Shana Werner’s father, Thomas DeFilippo, told police his daughter had spent Monday at his house on School Street in Marshfield helping him with his landscaping business, according to the report written by State Police Trooper Patrick M. McNamara.

She left at about 5:45 p.m., telling DeFilippo she planned to have dinner with her boyfriend, John Tallent, who she lived with in Marshfield, the report said.

About six minutes after Shana Warner left DeFilippo’s house, Marshfield police took a call from a woman who reported a man had jumped into a vehicle and fled on School Street, McNamara wrote. Police received Shana Warner’s frantic 911 call at 6 p.m.

Several witnesses who were near the intersection of Main Street and Old Main Street Extension at the time of the attack told police about the scene unfolding on the side of the road.

A female witness said she saw a woman on the ground yelling, “help, help, help” near the passenger door of a silver SUV, McNamara wrote. The woman started to walk away, the witness said, but the vehicle drove into her and dragged her.

A man then exited the SUV and ran away, Elumba said.

Another witness who was driving through the area said he saw two vehicles: an SUV that had driven off the road and a small silver sedan on the right shoulder, the report said.


A man carrying what appeared to be a stick exited the silver sedan and approached the SUV, according to the witness, who said he then heard a loud bang, believed to be gunfire, followed by a woman screaming, McNamara wrote.

The man got back into the silver sedan and sped away, passing vehicles on the wrong side of the road, Elumba said. The witness said he followed the silver sedan, took down its license plate number, and then returned to the intersection of Main Street and Old Main Street Extension, where he approached police about what he saw, the report said.

Police checked the license plate and learned the sedan was registered to Allen Warner’s mother, Sandra Warner, who lives in Quincy.

When investigators interviewed Sandra Warner about four hours after the killing, she said she had heard that her son “had been involved in a shooting incident with his estranged wife,” McNamara wrote.

“I’m sure Allen did it. I’m sure he did it. She just drives him up the wall,” Sandra Warner told investigators, according to the report.

Allen Warner’s roommate, Joseph Burton, told detectives he was complaining about his estranged wife on the morning of the murder, McNamara wrote.

“She is really getting me heated,” Burton quoted Allen Warner as saying.

Court records show the couple married in February 2008 at a wedding chapel on the Las Vegas strip, but friends and relatives told investigators they had a volatile relationship.


Shana Warner filed for divorce in June 2011, complaining that her husband had become physically and verbally abusive “due to his drug use,” and again in February 2017, court records show. Both cases were dismissed at Shana Warner’s request.

She filed for divorce a third time in May.

Police arrested Allen Warner Tuesday afternoon following an 18-hour manhunt. The search ended peacefully Tuesday afternoon in Whitman when he commandeered a flatbed truck and crashed it at a Dunkin’ Donuts. A Whitman police officer arrested him at about 12:32 p.m.

Defense attorney J. Drew Segadelli said his client’s connection to the killing is “tenuous at best” because witnesses didn’t identify Allen Warner as the suspect.

“As far as I’m concerned, this is still as some would refer to as a ‘whodunnit,’ ” he said.

On Sept. 20, police said Allen Warner dressed in camouflage attire and went to DeFilippo’s neighborhood to look for his estranged wife during heavy rain. When officers approached him, he said he was looking for cans, Tavares said.

Shana Warner's daughter, Victoria Taylor, told police her mother worried after filing for divorce and feared her husband may kill himself, McNamara wrote. She said she called Allen Warner’s cellphone twice Monday night because she believed he knew what happened to her mother, but the calls went to voice mail.

Taylor couldn’t think of anyone except Allen Warner “who would have done this to her mother,” McNamara wrote.
