WILTON, Maine — The grandmother found dead Saturday afternoon in the backyard of her home died from blows to the head, according to a spokesman for the Maine medical examiner’s office.

Dana M. Craney, 22, was charged with murder Sunday morning in connection with the death of his grandmother, Joanne Goudreau, 67.

“The cause of death is blunt force trauma to the head and it’s been ruled a homicide,” Mark Belserene said Monday.

Craney told police that he bludgeoned Goudreau to death with a hammer, striking her in the head six or seven times in her bedroom while she slept, according to a Sun Journal report.

Goudreau’s body was found Saturday afternoon in the backyard of the mobile home she shared with her grandson after Wilton police officers were called by other relatives to check on the woman’s well-being, according to a press release issued by Stephen McCausland, spokesman of the Maine State Police. Her body was later transported to Augusta, where the autopsy was performed.

Craney was at the house at 1130 Weld Road when police arrived and was brought to the Farmington Police Department for questioning. Police consulted with the Maine Attorney General’s office before charging Craney with murder. Craney is being held at the Franklin County Jail.

Craney made his first court appearance Monday morning and is being held without bail, a jail official said.

The suspect’s father, Dana A. Craney, was convicted in 1993 of killing Leon Michaud, a 73-year-old used furniture dealer and auctioneer, according to Sun Journal archives.

Michaud was found shot to death in a culvert on a rural Auburn road in 1990.

Dana A. Craney and Willard Eastman, 41, of North Carolina were not arrested until two years after the slaying when Craney’s estranged wife called police about his involvement in Michaud’s murder. Dana M. Craney was five months old when his father was arrested.

The Associated Press reported that witnesses in the trial against the elder Craney testified that he admitted killing Michaud for money on Dec. 20, 1990, because his rent was due and because he had no Christmas presents for his children.

Both Dana A. Craney and Eastman were convicted in Michaud’s death in 1993. Craney, now 52, and Eastman, now 63, are serving their sentences at the Maine State Prison in Warren, the Sun Journal reports.
