Richard Kos, 53, of 18 Green Springs Drive, was charged with conspiracy to tamper with or fabricate evidence, second-degree reckless endangerment, and permitting minors to possess alcohol. Susanne Kos, 52, was charged with second-degree reckless endangerment, and permitting minors to possess alcohol, and James L. Kos, 19, was charged with tampering with or fabricating evidence, and possession of alcohol by a minor. An arrest warrant was issued for a fourth family member, Matthew L. Kos, 27, who is out of state, on a charge of permitting a minor to possess alcohol.
A fifth man, Christian Stockinger, 19, of 11 Tuthill Street in West Haven, was charged with tampering with or fabricating evidence, and possession of alcohol by a minor.
All of the local suspects turned themselves in voluntarily to Madison police and were released on $5,000 non surety bonds. They are scheduled to appear in New Haven Superior Court on January 18.
Police have said Richard and Susanne Kos were home during a party where underage drinking allegedly took place. Jackson, a West Haven resident, died early on the morning following the party. Jackson was among the group of young people who were drinking at the house.
Authorities say no ambulance was called when Jackson was in need of medical attention that morning. Instead, he was transported by someone who attended the party to the Yale-New Haven Shoreline Medical Center in Guilford. The staff at that facility attempted to revive Jackson, but were unsuccessful.
