A 2-year-old boy reported missing Saturday morning in Northeast Portland has been found.

The child, River Schomaker, was found at about 11:45 a.m. in blackberry bushes about two blocks from his home, believed to be an apartment near 1700 N.E. 67th Avenue, two blocks south of Rose City Golf Course. The child was brought to a hospital for exposure to cold temperatures and scratches from the bushes, Portland police said.

Portland police, Beaverton police and Federal Bureau of Investigation agents and about 50 search and rescue volunteers scoured the immediate area for several hours before finding the child.

A Portland police news release did not mention why officers from Beaverton and the FBI would get involved in the case, but said, "Investigators will forward all police reports to the Oregon Department of Human Services for review, which is standard in any case involving child welfare."

The child's mother, Hollian Markusen, 27, and father, Aaron Schomaker, 28, told The Oregonian/OregonLive in separate phone interviews that they did not see the child before he was loaded into the ambulance. Both said they were unsure when they would be allowed to visit the child at the hospital.

"I'm pretty beside myself. I'm devastated. I'm scared," Markusen said, while weeping. "My son was lost. My beautiful, 2-year-old boy who've I've never been away from for more than a couple of hours his entire life."

Schomaker expressed gratitude for searchers' help. "It's an awesome thing to see these people who don't know me and they're out looking." He said search canines sniffed a bag containing a shoe and shirt belong to River before commencing the search.

Schomaker said he arrived at the couple's two-floor condominium at 4:50 a.m., returning from his job at Momo's in Southwest Portland. A Momo's employee told The Oregonian/OregonLive that Schomaker is a bartender.

He said he went to a separate room to sleep and then was awakened by Markusen screaming that the child was missing.

Markusen contacted police, Schomaker said. He said the couple left the condominium after contacting authorities to search for the toddler.

Schomaker said he believes the child was able to open a ground-floor entry door to venture into the outside. Schomaker said he planned to place a child-proofing device on the door Saturday.

Schomaker said he did not know why the FBI and Beaverton police would participate in the search and investigation. Markusen ended the phone interview with The Oregonian/OregonLive when asked the same question.

Earlier Saturday, a Portland police news release said the child's mother reported her son missing at about 6 a.m. Saturday, saying she awoke and found he was not in bed with her.

Twitter posts credited a Mountain Wave Search and Rescue volunteer named "Becky" and her German Shepherd with finding the child.

"He was found behind the market at 68th and Broadway, at a dead end there," Portland police Sgt. Jeff Helfrich said, referring to Pacific Supermarket, 6750 N.E. Broadway St.

"This is a great reminder for all parents who have kids," Helfrich said. "Make sure you have child safety locks on your doors If you have adventurous kids, make sure you take care of those... this is one that could have ended very tragically."

Portland police issued a news release at 8:11 a.m. Saturday asking for the public's assistance in finding the 2-year-old. About an hour later, officers were stretching crime scene tape at intersections encompassing a six-block area near the child's home.

Nevertheless, anxious neighbors viewed the unusual scene from afar, eager to hear the latest about the missing child.

"I just hope he's curled up in the laundry room, or something like that," said resident Tara Goddard, 37, who was looking around the neighborhood for the child with her dog, Smoky.
