UXBRIDGE (AP) - A Douglas man has been ordered held without bail after pleading not guilty to manslaughter in connection with the death of his wife.

Allen Stilkey, 40, and his wife, Lisa, were involved in a violent argument inside their Douglas home late Thursday night that involved broken furniture and glass, Worcester District Attorney Joseph Early Jr. said Monday after the arraignment in Uxbridge District Court.

Lisa Stilkey, 44, threw a pillow out a second-floor window before jumping out herself in an attempt to flee from her husband, Early said. She suffered severe injuries and was taken to a hospital where she was pronounced dead.

Allen Stilkey had recently taken out a life insurance policy in his wife's name and can be heard in a phone call Lisa Stilkey made to a relative threatening to kill her, prosecutors said.

Allen Stilkey was arrested later Friday and held over the weekend on $500,000 bail.

In addition to manslaughter, he has been charged with assault and battery and threatening to commit a crime.

There is no evidence to support the manslaughter charge and his client is not responsible for his wife's death, Stilkey's lawyer said.

According to the American Armsport Association website, Stilkey took first place in his weight class at the group's 2010 national championships held in San Antonio, Texas. He has also won regional events.
