BANGOR (AP) – A man charged with murdering a woman whose body was discovered last weekend killed her in his apartment and then toted her remains away in his landlord’s wheelbarrow, according to a police affidavit released Thursday.

Ashton Moores, 59, of Bangor, admitted to detectives that he killed Christina Simonin, according to the affidavit. The 43-year-old victim, the affidavit said, died from “multiple traumatic injuries.”

Moores was returned to the Penobscot County Jail on Thursday after making his initial appearance in court.

The victim’s body was discovered Saturday evening near her Union Street apartment. Two teenagers who found the body said it was wrapped in a comforter and a tarp and then placed in a plastic bag. One of them described the body as “mangled.”

Police said Moores’ most recent address was not far from where the body was found. According to the affidavit, Moores told police he killed Simonin in his apartment before hauling her body away in a wheelbarrow and dumping it.

The image of a man using a wheelbarrow to move a blue bundle was captured late Friday by a surveillance camera outside a homeless shelter near the location where the body was found, according to the affidavit by Detective Tim Cotton.

A similar wheelbarrow that belonged to Moores’ landlord tested positive for blood, and blood also was found on a baseboard in Moores’ apartment, he wrote.

Moores’ criminal history consists mostly of setting fires, including one that claimed the life of a 76-year-old man in Orono in 1973. Moores was released after serving eight years of a 10-year sentence for the fatal fire.

Within months he was charged with setting five fires in Waterville. He completed the sentence in that case in 1989.

A series of Belfast fires that began in October 1989 was tied to Moores, who served 30 days in jail for a Belfast assault in 1991.

He pleaded guilty to arson and was sentenced to prison again in 1995 after admitting to setting a fire at his girlfriend’s Belfast apartment in 1994 and another fire at his parents’ Belfast apartment in 1993.

In 2006, Moores was convicted of criminal mischief in Bangor.

According to the affidavit, police quickly zeroed in on Moores and questioned him on the night her body was discovered. Simonin had told family members that she was being evicted and Moores said she’d stayed in his house briefly.

Moores initially told police he’d last seen her on Feb. 15. But he changed his story after he learned that a police officer had seen her on Feb. 24, the affidavit said.

In Stetson, the victim’s mother, Harriett Ross, said her daughter was worried that she was living in an unsafe neighborhood. The last contact Simonin had with her family was two weeks before her body was discovered.

Ross said she wants answers. “However she died, she didn’t deserve it,” Ross said. “I just want to know who did it and why.”
