Carlos Asencio, the New Hampshire man accused of stabbing his former girlfriend to death at O’Connor’s Restaurant in Worcester, reported hearing voices in his head over the past two years, according to a court clinician.

Asencio, 28, of Derry, New Hampshire, was sent to Bridgewater State Hospital to undergo a 20-day mental health evaluation following his arraignment in Central District Court in Worcester. He is facing numerous charges, including murder, after authorities said he stabbed 31-year-old Amanda Dabrowski to death Wednesday night.

Not guilty pleas were entered on his behalf.

Police say Asencio entered O’Connor’s Restaurant on West Boylston Street Wednesday around 7:50 p.m. and stabbed Dabrowski 15 to 20 times. Dabrowski, who was in and out of consciousness when police arrived, court documents said, was taken to UMass Memorial Hospital where she was pronounced dead at 11:42 p.m.

Asencio is also accused of stabbing a male patron who rushed to help the woman.

That man sustained injuries that are not believed to be life-threatening.

Prior to Asencio’s arraignment, his lawyer, Attorney Robert Griffin, requested that his client undergo an evaluation by a court clinician. Judge Steven Power granted the request.

Several hours later, forensic psychologist Dr. Stephanie Hansen told the court that Asencio reported experiencing auditory hallucinations over the past two years, as well as an increase in anger and explosive episodes over the past several months.

“Based upon the limited but available information, the defendant does report a long history of depression that has generally remained untreated for the past several years and has resulted in at least one suicide attempt back in 2008,” she said.

Hansen also said that Asencio reported putting a knife to his throat recently while having thoughts of suicide.

Judge Power ordered Asencio to undergo a 20-day evaluation at Bridgewater State Hospital. He is due back in court July 25 for a status hearing.

Asencio was also ordered held on an outstanding warrant out of Ayer District Court.

Several of Dabrowski’s family members sat in the front row during the arraignment and left immediately following the judge’s decision. They have declined to comment on the case.

Asencio is accused of going to O’Connor’s Restaurant Wednesday night in search of Dabrowski, who was there with two other women attending a book club.

Surveillance video from inside the restaurant showed Asencio entering the restaurant and walking back and forth looking for Dabrowski, who was in the bathroom at the time. When she exited the bathroom, the two met at the ramp exiting the restaurant. Surveillance footage then shows Asencio stabbing Dabrowski soon after, according to court documents.

Authorities said Wednesday’s fatal attack was at least the second time Asencio harmed the victim.

In April, the Middlesex District Attorney’s Office said he broke into her house in Ayer during the early hours of the morning and attacked her with a stun gun. Authorities said Asencio was wearing a mask and had a handgun at the time of the attack.

Asencio fled to Canada and then to Mexico after the attack, according to the District Attorney’s Office.

Massachusetts authorities contacted Border Patrol in Canada the day of the home invasion and were notified that Asencio had crossed the border into Canada and allegedly boarded a 1:30 p.m. flight to Mexico, the Middlesex District Attorney’s Office said. Police obtained and executed a search warrant at his home and applied for an arrest warrant for Asencio on April 25.

Ayer Police and the Middlesex District Attorney’s Office notified the United States Marshal’s Service and federal border patrol authorities to make them aware of the warrant and to ask for help capturing Asencio and bringing him back to the United States, authorities said.

The arrest warrant was entered into The National Crime Information Center.

Over the next month, investigators learned that Asencio was likely still in Mexico, according to the District Attorney’s Office.

Authorities said that investigation is ongoing and Asencio was never arrested in connection with the home invasion and stun gun attack. His reentry into the country is under investigation by federal authorities.

Asencio is charged with murder, assault and battery with a dangerous weapon, armed assault with intent to murder, disorderly conduct, disturbing the peace, resisting arrest and an outstanding warrant stemming from the April attack.
