PLYMOUTH – A Rockland man was held without bail and ordered to undergo a mental health evaluation after he was arraigned on charges that he allegedly murdered his estranged wife, Plymouth County District Attorney Timothy J. Cruz and Marshfield Police Chief Phil Tavares announced.

Allen Warner (DOB: 10/22/70) of Rockland was arraigned in Plymouth District Court today on one count of Murder. Judge James Sullivan ordered Warner held without bail and agreed with the court appointed clinician’s opinion to send Warner to Bridgewater State Hospital for a 30-day mental health evaluation.

At approximately 5:51 pm on Monday, Marshfield Police received two calls reporting that a motor vehicle was off the road and a carjacking or domestic violence incident was occurring in the vicinity of 758 Main Street, Route 3A. The third call, a 911 call, to Marshfield Police was made by the female victim, 48-year-old Shana Warner of Marshfield. She reported to police that her ex husband had jumped in the car and she was very hurt. Police responded to the area and located Shana Warner suffering from life threatening injuries. She was transported to South Shore Hospital where she was pronounced dead of her injuries at 6:43 pm.

Interviews on scene indicated that the perpetrator, later determined through the investigation to be Allen Warner, may have fled into the woods. A perimeter was set up and numerous state, local and federal agencies, K9 and Massachusetts State Police Air Wing responded to support the effort to locate the suspect.

As a result of the investigation, information was developed indicating that the victim’s estranged husband, Warner was a person of interest and a BOLO was issued by Massachusetts State Police on Monday evening for Warner and the vehicle he was traveling in, a 2013 gray Toyota Corolla with the Massachusetts registration #4FSZ80.

On Tuesday, at approximately 12:30 pm, Whitman Police were alerted to a hit and run with property damage at a business. Witnesses reported seeing Allen driving a
ramp truck from a local business. Whitman Police responded to the business and while there, Allen drove into the business with the ramp truck. Police asked him if he was Allen Warner and he confirmed his identity and was placed under arrest without incident.

The Office of the Chief Medical Examiner will determine an exact cause and manner of death and those results are pending. The Chief Medical Examiner made a preliminary determination that Shana Warner was stabbed six times and shot with a firearm once.

Allen is next scheduled to appear in court on October 15, 2018.

The case is being prosecuted by Assistant District Attorney Jessica Elumba and was investigated by State Police Detectives assigned to the Plymouth County District Attorney’s Office.
