MILTON TOWNSHIP, Mich. (WOOD) — Deputies have identified the victim of a Friday afternoon drowning on Elk Lake as an 18-year-old from Grand Haven.

The 18-year-old was identified as Sendy Grettenberger of the Grand Haven area, the Antrim County Sheriff’s Office said.

Just before 3 p.m., Antrim County Sheriff’s deputies were sent to the public access on Easley Road near Cherry Avenue after receiving reports of a man, later identified as Grettenberger, who was in the water yelling for help.

When first responders arrived, he was no longer visible, the sheriff’s office said.

Emergency boats were immediately put in the water as emergency crews looked for Grettenberger and dive teams were called.

Divers found Grettenberger just after 8:30 p.m. in approximately 25 feet of water, the sheriff’s office said. He was not wearing a life jacket.

The sheriff’s office said Grettenberger had gone out on a small rowboat to read. Shortly after his sisters heard him yelling for help. It’s unclear why or how he fell out of the boat.

The drowning remains under investigation.
