Authorities have recovered three bodies from Henry Hagg Lake following the drowning of a 3-year-old boy Monday, according to the Washington County Sheriff's Office.

On Tuesday morning, officials said they were searching for three of the boy's family members – two adults and another child. Authorities found a 13-year-old boy, 25-year-old woman and 42-year-old woman in the water.

The 25-year-old woman was the 3-year-old's mother, according to the sheriff's office, and the 42-year-old was his grandmother. The teen boy and younger woman were siblings. The family lived together in Hillsboro.

Investigators suspect that the boy's family also drowned and have not found any signs of foul play, said Sgt. Bob Ray, a sheriff's office spokesman.

Ray did not provide additional information about the boy's family members.

About 6 p.m. Monday, two people who were fishing in the area spotted the 3-year-old boy, who was unconscious near the shoreline where Sain Creek flows into Hagg Lake.

They pulled him from the water to a picnic area. They reportedly performed CPR on the boy until Gaston Rural Fire District crews arrived, Ray said. The boy died at the scene.

Deputies searched for the boy's parents or family members, but they couldn't find them. They found a beach towel, cooler, shoes and other items on the beach, close to where the boy was discovered.

Authorities ended their search about 10:30 p.m. Monday and resumed the effort Tuesday morning. A Clackamas County Sheriff's Office dive team responded to help.

This story will be updated as more information becomes available.
