PROVIDENCE, R.I. (AP) – A man who allegedly shot a detective to death inside police headquarters was ordered held without bail Monday on a murder charge.

Esteban Carpio, 26, did not enter a plea in Providence District Court to a charge that he killed Det. James Allen Sunday inside police headquarters as Allen interviewed him about his possible involvement in the stabbing of an 84-year-old woman.

Police said Carpio, who was not handcuffed, got hold of Allen’s gun, shot him twice, broke a third floor window and jumped out. He was captured after a struggle a few blocks away, police said.

Carpio, his face badly swollen and disfigured from bruises, appeared in court on Monday wearing a white, plastic mask that obscured the bottom half of his face.

As he was brought into the courtroom, hands and legs shackled and held by several officers, his mother and another woman began wailing. One yelled, “Oh my God, look what they did to him.” Sheriffs wrestled both women from the seats and out of the courtroom as they screamed about police brutality.

A third woman remained in the courtroom, hands over her mouth, rocking in her seat. After the arraignment she yelled, “I love you, baby,” at Carpio.

Carpio nodded his head to respond to questions during his arraignment, but did not speak, except to say “I love you, Mom,” as he was led out of the courtroom.

The single charge of murder carries a maximum sentence of life in prison without parole because it involves the alleged killing of an on-duty police officer, according to Providence police. The case will now go to a grand jury.

Police Chief Dean Esserman said Monday there was no indication that police used excessive force to subdue and arrest Carpio.

“He jumped out of a third-story window and he struggled in a fairly tough struggle on the ground” when Providence and state police and federal agents caught him, Esserman said. “When I saw him he was fairly cut up.”

Department of Corrections spokeswoman Joy Fox said Carpio was wearing the mask, called a spit shield, as a precaution. She said the shields are used when a prisoner is bleeding or if there are concerns he might be combative. Carpio was being held in segregation at the Adult Correctional Institutions with a 24-hour guard.

On Monday, Esserman again declined to say how police think Carpio managed to get Allen’s weapon. He also would not discuss police protocols for carrying weapons inside headquarters or for interviewing potential suspects.

His family said Carpio had recently been experiencing mental problems. Esserman would not comment about whether police had been told on Saturday, before the shooting, that Carpio was mentally unstable.

“He needed help and we couldn’t get it and we tried and tried,” Dolores Irish, who identified herself as Carpio’s aunt, said outside court Monday morning. “He didn’t deserve this. He’s a victim just as much as anybody else in this.”

A man who identified himself as Carpio’s uncle but would not give his name said outside court that the family had tried to get Carpio psychiatric help. The uncle said Carpio recently had been admitted to then released from several facilities.

The uncle said the family was sorry for what had happened, and also said it was clear from Carpio’s injuries Monday that he had “obviously been beaten very badly.”

Esserman said the department would review Carpio’s treatment if appropriate, and would consider a review by an outside agency.

“If (Carpio’s relatives) have allegations, if they have concerns, we will not be deaf to that,” Esserman said.

Allen, 50, of Johnston, was married and had two daughters, and had been a police officer for 27 years. The chief of detectives, Maj. Stephen Campbell, said Allen was smart, hardworking and kind.

“Jimmy never missed a call. Jimmy never said no,” Campbell said.

Esserman said Allen’s shift had ended at 4 p.m. Saturday, but he had gone out, gotten a meal, and returned to work to keep investigating the Saturday afternoon stabbing.

“I’m going to have to live with that, because I’m the one who asked for us to pull out all the stops on this case,” said Esserman, who said he spoke with Allen hours before the shooting.

Esserman said no charges have been filed in the stabbing, and Carpio remains a suspect.

A funeral mass was scheduled for 11 a.m. Wednesday at St. Thomas Church in Providence.
