ROCKLAND, Maine — A Rockland man accused of strangling a Friendship woman 16 months ago has denied that he violated terms of his probation.

Arnold A. Diana, 36, appeared in Knox County Superior Court on Monday to respond to a request by the state that the court find that Diana violated his probation from a 2009 domestic violence assault conviction. The state has argued that he violated his probation by committing new criminal conduct — the Nov. 20, 2010, murder of 47-year-old Katrina Windred of Friendship.

Diana denied the allegation in court on Monday and was ordered to remain imprisoned without bail on the murder charge.

Diana was convicted in January 2009 of assaulting a woman who lived in his household in Rockland. He was ordered to spend 90 days in jail, which was all suspended, and he was placed on probation for two years. One of the conditions of probation was that he refrain from additional criminal conduct.

The state had filed the probation revocation motion in June 2011 but Diana had yet to have a court appearance on that matter.

There also are pending motions under review by Justice Jeffrey Hjelm in the murder case. A hearing was held last August and further filings were made later in the fall in defense efforts to keep some evidence from being presented at trial. The defense has argued that Diana was not given his Miranda warnings against self incrimination each time he was questioned by police. His attorney also has challenged the affidavit used to get a search warrant of Diana’s apartment at the Thorndike apartments on Main Street in Rockland.

According to police reports filed in court, Windred had stopped by Diana’s apartment to deliver groceries as her 9-year-old son waited in a car outside the building. Diana told police that the two had an argument and he grabbed her, possibly in the neck area, and they fell to the floor. He claimed to police that she was breathing but unconscious when he placed her face down on his bed. He then allegedly took her ATM card and withdrew money from her account and invited the woman’s son into his apartment, telling him that his mother had taken a nap.

Once the child fell asleep, Diana wrapped Windred’s body in a blanket, dragged her body down the stairs to a friend’s truck that was parked in the parking lot and later drove to Thompson Meadow Road in Rockland and dumped her body along the side of the road, according to police.

Diana later took the boy, who was unharmed, to his father, telling them both that Windred had left to visit friends and not returned to pick up her son, police reported.

Windred’s boyfriend had called police the night of Nov. 20, 2010, when she did not return from Rockland. Police eventually questioned Diana and arrested him after her body was located Nov. 23 and after further investigation.
