(Portage) Two people are charged with felonies in Columbia County after authorities say they “viciously” attacked two police officers. Portage Police Sergeant Eric Walters lost consciousness when he was kicked in the head. Witnesses say 21-year-old Olivia J. Boomsma punched Officer Brian Loewenhagen in the face several times while he was trying to take her companion into custody. Twenty-one-year-old Jacob Hellenbrand was wanted for a probation violation. The incident happened Sunday night at a convenience store in Portage. An off-duty nurse started helping the unconscious police sergeant and reportedly body-slammed Boomsma, holding her until an officer could handcuff the suspect.
