SKOWHEGAN — A man suspected of killing his father in Cambridge was cooperative and willing to talk for a while when he turned himself in to police, an investigator said in court Tuesday.

Angelo Licata, 34, of Detroit, came voluntarily with two friends to the Waterville Police Department on July 21, said Maine State Police Detective Bryant Jacques, who met Licata at the police station to discuss the circumstances surrounding his father’s death.

Licata signed paperwork agreeing to waive his Miranda rights to remain silent and have an attorney present, and then answered questions, Jacques told Judge John Nivison in Somerset County Superior Court.

Licata’s father, Alfred Licata, 63, had been found dead on a lawn near his home several hours earlier. The medical examiner later determined he died of blunt force trauma to the head.

After Tuesday’s testimony, Nivison will decide whether to suppress certain statements made by Licata to police.

Defense attorney Peter Barnett asked that all of Licata’s discussions with police on July 22, which were audio-recorded, be suppressed because Jacques did not read him a clear Miranda warning and coerced him into signing a waiver of his rights.

“He was pressured under the threat of arrest to answer questions,” Barnett said.

Assistant Attorney General Andrew Benson argued that some of the interviews should be allowed because Licata said he wanted to answer questions and signed the waiver voluntarily.

Waterville Police Sgt. Daniel Ames, the first officer to testify, said Licata arrived after midnight at the police station and said he wanted to turn himself in, but didn’t want to talk without a lawyer present. Ames told Licata someone would be with him shortly.

When Jacques arrived, Licata agreed to talk with Jacques in his police cruiser.

Jacques said he read Licata the Miranda warning, and Licata agreed to an interview.

Around 3:27 a.m., Jacques said, he returned to conduct a second interview and told Licata he was not free to leave. When asked whether he was responsible for the death of his father, Licata declined to answer, and was taken to Somerset County Jail.

The next evening, Jacques said he got word that Licata wanted to see him at the jail. Jacques said that the next day, he read Licata his Miranda rights again. Jacques said Licata declared that he wanted the truth known. In particular, Licata said “the Lord” wanted it known, Jacques said.

Jacques did not provide details. He said he never made any promises to Licata to get him to talk, and he never raised his voice or threatened him.
