MADRAS – A Culver man accused of shaking his 4-month-old infant nearly to death was arraigned on charges of first-degree criminal mistreatment and second- and third-degree assault on Thursday in Jefferson County Circuit Court.

Pedro Coreas-Castro, 25, of Culver, was being held at the Jefferson County Jail on $100,000 bail Thursday.

His daughter was on life support at St. Charles Medical Center-Bend on Thursday evening and is not expected to live as the result of brain injuries, according to an affidavit filed by a sheriff’s detective.

Coreas-Castro’s attorney, Jennifer Kimble, said he has pleaded not guilty. Coreas-Castro is scheduled to next appear in court on July 8 at 11:30 a.m., when an indictment will likely be filed, Jefferson County District Attorney Peter Deuel said.

An affidavit filed by Detective Scott Farrell and a Jefferson County Sheriff’s Office press release gave the following account of the incident:

On Wed-nesday, Madras Police Officer Matthew Sherwood found the infant sitting in the back seat of a van that he stopped for speeding and running stop signs. The officer reported the baby was not breathing and didn’t have a pulse.

The infant was taken to Mountain View Hospital, where doctors established a pulse, and then the baby was flown by helicopter to St. Charles Medical Center-Bend for further treatment.

Coreas-Castro initially told the officer that the baby began crying and choking after he fed her a bottle of formula.

He decided to take the child to Mountain View Hospital in Madras because he didn’t have a phone in his Culver home.

Dr. Brenda Hedges of the St. Charles critical care unit told sheriff’s officials she found multiple area brain hemorrhages and an internal eye injury that was consistent with a serious assault of the infant, also known as ”shaken baby syndrome.”

Sheriff’s deputies arrested Coreas-Castro on Wednesday, after he admitted to shaking his baby to stop her from crying, according to the affidavit. According to the Oregon Judicial Informmation Network, Coreas-Castro has had two traffic violations.

The National Center on Shaken Baby Syndrome, a nonprofit group based in Utah, estimates there are 600-1,400 cases of the syndrome each year.

District Attorney Deuel said his office is still investigating the matter, but additional charges will likely be filed if the baby does not survive.
