Detectives investigating a rape case in Skagit County discovered videos on a former Oak Harbor man’s computer that appeared to show him sexually assaulting a child, according to court documents.

Investigators alerted Oak Harbor police about the videos earlier this month after concluding that the child was victimized in the city years ago.

On April 9, the police arrested John A. Holcomb, a Burlington resident, after he arrived at the Burlington Police Department for an interview. The next day, he appeared in Island County Superior Court and the judge found probable cause to believe he committed three counts of rape of a child in the first degree and three counts of possession of depictions of a minor engaged in sexually explicit conduct in the first degree.

The judge set bail for Holcomb at $500,000.

According to the police report, the Burlington Police Department was investigating Holcomb in a more recent rape case in which Holcomb had possibly videotaped sexual contact with the victim. Investigators seized two computers from him and discovered three video files that showed him repeatedly raping a grade-school girl, the police report indicates.

The investigators were able to identify the child by showing a still image from the video to the child’s mother, the report states.

The rape charge against Holcomb in Skagit County was dismissed, court documents state.
