Mom arrested in Yamhill County child abuse case

MCMINNVILLE, Ore. - The mother of a young boy that police say was viciously abused is under arrest.

Detectives arrested Brandy Lynn Robertson, of Sheridan, and she will be charged with criminal mistreatment and recklessly endangering another person. She is in Yamhill County Jail and will likely be arraigned on Monday.

The four-year-old boy was taken to Oregon Health & Science University on New Year's Eve with severe brain injuries, broken ribs, even torn intestines.

Robertson's boyfriend, a Yamhill police reserve officer named Michael Abo, stands accused of abusing the young boy for weeks. He was arrested Jan. 4.

Documents show investigators believe Abo had been targeting his girlfriend's son since they moved into his Sheridan home in early December.

Abo claimed the boy fell down the stairs, but documents show doctors told police that story isn't adding up.

"To me he's the scum of the earth," said Ruby Swartz, Abo's neighbor.

"I always thought he was bullying me, especially when he came by with his pistol on," Swartz said.

But Abo's friend, who only wanted to be identified as Mary, says there's no way these allegations are true.

"I've never known of him to be a violent person. He's been around my kids. I've been around his kids. I've never seen that action from him," Mary said.

Abo remains locked up on $1 million bail.

The Yamhill County sheriff fired Abo Nov. 19, 2012 after disciplining him and after issuing him warnings several times for failing to appear at trials involving defendants arrested for various crimes, according to the Department of Public Safety Standards and Training.

After Abo was fired, the DPSST opened an investigation, which it does automatically in cases like this.

Abo contended he missed two of the scheduled court appearances because of medical issues.

Still, after its investigation, the DPSST recommended that Abo's law enforcement certification should be stripped.

Abo requested an administrative hearing and a judge reviewed the case but proposed that Abo should be able to keep his certification.

The DPSST is considering the judge's proposal and the case has not yet been resolved.
