Cause of death still unknown

State Police investigate the home at 482 Rimmon Hill Road, where a body was found early Thursday morning.

BEACON FALLS — State police and the Office of the Chief Medical Examiner are still short on details about the body found Sept. 29 in a Rimmon Hill Road home. Police initially called the death “accidental” but had changed that rating to “suspicious” by Thursday afternoon.

An autopsy performed by the medical examiner’s office on Oct. 1 did not yield a definite cause of death, and a representative there said Tuesday the results are “pending further study” and it would be eight to 12 weeks before the cause of death is ascertained and made public.

State police said no new information was available as of Tuesday afternoon, noting the case is still under investigation.

Olga Louniakova, 25, was found dead at the address, which is about a half-mile from Woodland Regional High School, late Wednesday night. The Beacon Falls Resident State Trooper’s Office and State Troopers from Troop I in Bethany responded to 482 Rimmon Hill Road after receiving a suspicious call, and EMS personnel declared Louniakova dead at the scene.

According to the assessor’s office, the house is owned by Jacqueline and Dennis Molen, whose telephone number is unlisted.

Two years ago, Louniakova pleaded guilty to charges of second-degree threatening and second-degree reckless endangerment. Police charged her with those crimes, both misdemeanors, in addition to criminal attempt at second-degree assault, for allegedly poisoning a teacher’s water bottle with Visine eye drops in March 2008.

She was sentenced in July 2008 to six months jail time, execution suspended, with two years probation for the reckless-endangerment charge, and received one year in jail, execution suspended, with two years probation on the threatening charge, according to Connecticut Superior Court records.
