A Lincoln police officer accused of sexually abusing four family members when they were minors was arraigned in Sacramento County Superior Court on Tuesday.

In June, the Sacramento County Sheriff's Office said that it got a call that four females were sexually abused years earlier by a family member identified by authorities as 52-year-old Timothy Jaekel. As a result of the investigation, Jaekel was arrested on October 16 and booked into Sacramento County Jail without bail. 

Deputies spoke with the primary victim, who is living in Arizona. The victim said that she had already contacted the Lincoln Police Department and told them about the abuse, as deputies said Jaekel was an active police officer at the department. 

Four victims were interviewed, deputies said, disclosing "a long-term pattern of being touched by Jaekel over and under the clothing between the ages of 8 and 16, in Sacramento County."

Deputies said Jaekel asked one of the victims for nude pictures of herself when she was a juvenile. The victims also reported witnessing Jaekel inappropriately touch other female family members, deputies said. 

The Lincoln Police Department said Jaekel remains on unpaid administrative leave while the investigation remains ongoing.
