A woman from Bangor accused of trying to suffocate a 97-year-old woman at a nursing home remains behind bars on $50,000 cash bail. Prosecutors say 49-year-old Jodi Lynn Holmes has a history of making threats against the elderly. She was convicted of making bomb threats against three local schools in 2007. Today in Bangor, Holmes made her first court appearance on the suffocation case, via video.She’s charged with aggravated assault.Police say they were called to Bangor Nursing and Rehabilitation Sunday.They were told a woman walked into the room of a 97-year-old patient and tried to smother her with a pillow, then ran away.The woman wasn’t seriously hurt. Deputy District Attorney Mike Roberts says this case is troubling and unusual.”The elderly have been victims of crimes, obviously, before but this sort of random attack on an elderly person for no other basis than to cause physical harm would be new to me.”Holmes was on federal probation after serving two years in prison for the bomb threats. As part of the probation, she was ordered not to be around elderly. The judge today ordered that if Holmes makes bail, she’s not allowed to be at nursing home or assisted living facility. Holmes is in the Penobscot County Jail and is due back in court in April.
