A western Massachusetts woman is asking the state’s highest court to find her not guilty of killing her wife in 2010. Jurors deadlocked in the two previous trials of Cara Rintala.

Monday, Rintala’s attorney David Hoose conceded that Rintala did have the opportunity to murder her wife, but she was not the only possible person. There’s compelling evidence, he said, that the assault that lead to Anne Marie Rintala’s death took place at the side entrance of their Granby, Mass., home, not in the basement where her body was found. Whoever committed the murder, Hoose said, had to have the strength to get the victim to the basement door, push her down the stairs, and then strangle her, a strength Hoose claims Cara Rintala doesn’t have.

“The defendant in this case is about 5′ 6″ tall and about 125 pounds. The deceased outweighed her by 60 to 70 pounds,” Hoose said in court. “And according to [Cara Rintala’s] long term girlfriend, who testified as part of the Commonwealth’s case,” Hoose told the justices, “she was, quote unquote ‘wicked strong.'”

Hoose wants the SJC to rule the prosecution presented insufficient evidence and find her not guilty.  The Northwestern District Attorney — who says Rintala committed the murder, tried to clean the crime scene and then stage a break-in — wants to try Rintala for a third time.
