BELFAST, Maine — A Belfast woman accused of shooting her husband to death two months ago has been released on bail, Waldo County Jail officials confirmed Friday.

Amber B. Cummings, 31, had been held at the Belfast jail since Feb. 13, when she turned herself in to authorities after being indicted on a murder charge by a Waldo County grand jury. During her arraignment on Feb. 17 in 5th District Court, Cummings pleaded not guilty by reason of mental disease in the shooting death of her husband late last year.

According to jail officials, Cummings was released on $50,000 cash bail, with several conditions.

Details about bail conditions were not immediately available Friday evening.

State police investigators say that Cummings shot her 29-year-old husband, James G. Cummings, in the couple’s High Street home on Dec. 9 in what they described as a domestic violence homicide.

The couple’s 9-year-old daughter was in the home at the time of the shooting.

A police search of the Cummings home after the murder turned up radioactive materials and instructions for building a dirty bomb. State officials have said that the materials posed no danger to the public.

An internal FBI memo that was leaked from the Washington Regional Threat and Analysis Center and posted on the Internet last month stated that evidence removed from the home linked James Cummings to dirty bombs and a white supremacist group.

The FBI memo said Amber Cummings told investigators that her husband talked about dirty bombs and mixed chemicals in their kitchen sink.

She said she had endured years of mental, physical and sexual abuse at the hands of her husband, according to the memo. It also indicated she told police that her husband was “very upset” when Barack Obama was elected president.

The Cummingses grew up and were married in Fort Bragg, Calif., before leaving there for Texas and eventually Belfast. They moved to Belfast in August 2007 after buying their home in a foreclosure sale for $153,900.

James Cummings was the son of a wealthy Fort Bragg real estate owner who was murdered by a former employee in 1997. The FBI report said Cummings bragged of inheriting $2 million from his father.
