ISLIP, N.Y. YORK (CBSNewYork) — Detectives with the Suffolk County Police Homicide Squad are investigating the death of an 18-year-old man who was found in an Islip marsh Saturday morning.

Kyle Underhill’s grief stricken family and friends had been worried about the teen since Wednesday night, when he was last seen alive on Brook Street. The next day his family went to police to report him missing, resulting in a massive search in the woods and marsh.

LISTEN: WCBS 880’s Alex Silverman reports “Police cars, detectives, a lot of activity,” resident Rene Torres told CBS 2’s Dave Carlin.

Investigators found his body at 9:20 a.m. in a marshy area off of Brook Street. He was pronounced dead by an assistant medical examiner from the Office of the Suffolk County Medical Examiner.

“I really don’t know how this could happen,” said friend Brian Melton. “Some people liked him, some people hated him, and I don’t know what could have led this to happen.”

“It’s heartbreaking to hear. He’s one of us. He was in Islip School with us. Now he is no longer with us,” said friend Samantha Galardi.

Underhill, a recent graduate of Islip High School, caused a stir with what he wrote for the school’s yearbook. Under his photo was this quote: “I don’t think I’ve ever known so many people I hated so much all at once. See you in Abbadon.”

Abbadon commonly refers to the depths of hell.

Police believe Underhill may have been murdered but are not releasing cause of death or other additional details.

Undehill worked as a full time busboy at Tellers Restaurant in Islip. The managers told Carlin that he also worked part time at a nearby bakery and attended college in Farmingdale.

“Kyle Underhill was a bright, wonderful, gregarious and hard working member of the Tellers Chophouse family and he will be missed. Our thoughts and prayers go out to Kyle’s family and friends,” said the restaurant’s owner Michael Bohlsen.

Detectives are asking anyone with information about this incident to contact the Homicide Squad at 631-852-6392, call anonymously to Crime Stoppers at 800-577-TIPS, or visit
