GASTON, Ore. -- Searchers on Tuesday found three more bodies in Henry Hagg Lake after a boy was found drowned Monday, the Washington County Sheriff's Office said.
The bodies were identified as 42-year-old Jova Ixtacua-Castano; her 13-year-old son, Michael Garcia-Ixtacua; and her 25-year-old daughter, Gabriela Garcia-Ixtacua. The 3-year-old boy found on Monday was Jeremy Scholl, the son of Gabriela Garcia-Ixtacua and grandson of Ixtacua-Castano.
The family lived together in Hillsboro.
"This was a tragic thing and we're trying to put it together," said neighbor Dawn Medley. "We're a really tight-knit neighborhood."
"Detectives found nothing suspicious and no signs of foul play. This appears to be a tragic incident where someone likely got into trouble in the water and others attempted to help them," Sgt. Bob Ray with the Washington County Sheriff's Office said Tuesday. "Detectives are still searching for any answers that will help them understand the events that occurred yesterday evening to cause the deaths."
Surviving family also found a dog that belonged to the group near the lake and took it home.
Friends said the four came to Hagg Lake for what was planned as a pleasant day outing on Monday.
Authorities are still trying to determine how all four people ended up in the water.
Searchers found the three bodies in approximately eight feet of water, about 50 yards from where the 3-year-old boy was found Monday.
None of the family members was wearing life jackets.
Searchers looked for parents after boy found dead
Merlin Tague, who was visiting the area from another state, spotted a boy face-down in the water near the Sain Creek picnic area Monday evening.
"So I pulled him out, yelled at the people on the hill to call the cops, and then we started doing CPR right away," said Tague.
He and one other person performed CPR, but they were unsuccessful.
"It's a tough one," said Austin Sanders. "At least we found him before nightfall."
The sheriff's office had reported they could not locate the boy's parents and that's when divers were called in to begin searching for any sign of them.
Investigators noticed an unattended white car in a nearby parking lot. They were able to connect it to a picnic area that was also unattended.
Forest Grove Fire spokesman David Nemeyer said the items at the picnic table included a pair of adult flip flops and food. A photo of the boy was found inside the car.
Jeremy Scholl had no obvious signs of trauma. An autopsy was scheduled, according to the sheriff's office.
The search was resumed at 10 a.m. Tuesday. The additional bodies were found just before 12 p.m.
The entire lake was closed to the public.
If you know anything about this case you are urged to contact the Washington County Sheriff's Office at 503-629-0111.
