MCMINNVILLE, Ore. Police arrested the mother of a 4-year-old boy who was badly beaten and brain damaged on New Year s Eve, allegedly by a Yamhill reserve police officer, authorities said.
Brandy Lynn Robertson was charged with criminal mistreatment and reckless endangering after her son suffered a traumatic brain injury, as well as other traumatic injuries to his body, according to Matt Scales with McMinnville police.
On Jan. 4, Police arrested Robertson s boyfriend, 34-year-old Michael Shane Abo, on two counts of assault and two counts of criminal mistreatment. Abo is a Yamhill reserve police officer and former Yamhill County Sheriff s deputy.
On Dec. 31, deputies responded to Abo s home regarding an injured 4-year-old boy. The boy was then immediately flown by helicopter to Oregon Health & Science University where he was in critical condition.
Abo's police statement said the child was jumping up and down on the stairwell just before Abo went into his bedroom. Abo reported that he heard a thump and found the 4-year-old child laying on his back at the bottom of the stairwell.
Investigators did not believe Abo s story.
Doctors treating the boy told police the injuries were the result of blunt force trauma and would not be consistent with a fall from a stairwell, according to the court documents.
Robertson initially told investigators Abo was the only person with her son and no one else could have hurt him.

Abo was held in the Washington County Jail since he worked in law enforcement in Yamhill County and could be a safety risk. His bail was set at $500,000.
