Two people were found dead at the Amberwood Townhouses near Holland Saturday.

A man who lives at the house found the two victims, 27-year-old Teri Hills and 30-year-old Amber Janowiak, dead Saturday morning just before noon, according to Ottawa County Sheriff’s Office Capt. Mark Bennett.

It’s unknown how long they were dead. Authorities said there was no suspicious activity and no threat to the public.

Autopsy results show no obvious signs of foul play. Results are being sent off for toxicology testing to determine if alcohol or drugs contributed to the victim’s deaths.

Fire crews checked the air quality at the townhouse and have since ruled out carbon monoxide poisoning.
