Jason D. Reeser, 34, of Bremerton has been charged with assault of a child in the first-degree in a Jan. 28 incident involving the girl.
According to the statement of probable cause, medics responded to a home in the 3500 block of N. Shorthorn Dr. NW around 2:40 p.m. and found the girl in an "altered level of consciousness."
While being rushed to Harrison Medical Center in Silverdale, the girl suffered from "seizure-like activity, posturing and grinding her teeth," the document said.
Doctors determined the girl was suffering from sub-dermal hematoma. The girl was taken to Mary Bridge Children's Hospital in Tacoma where she underwent emergency surgery.
Doctors at Mary Bridge discovered an acute hematoma on right side of her head and determined the injury, which they feared "was not survivable," would have taken place in the past 24 hours, the statement said. A visible wound was also found on her leg.
When questioned by investigators, Reeser initially said he was unaware of any trauma the girl may have suffered while in his care. He said the girl was napping when he heard noise coming from her bedroom. He went to check on the girl, and found her having a seizure and vomiting, he told detectives.
Reeser later changed his story and admitted there had been an incident.
Reeser told detectives he had grown frustrated while changing the girl. He said he had "pulled too hard" on her leg, and ended up "pulling her entirely off the bed." The move caused the girl to hit her head on the floor, Reeser told police, and "she got that frigging look in her eye" before growing unresponsive.
Reeser had been living with the girl and her mother since September, according to the document. He is being held on $750,000 bail.
