MILWAUKIE, Ore. - Police arrested a former Milwaukie High School student they said raped or sexually abused four girls last last year while still a student.
The school's principal sent a letter to parents on Friday alerting them that London Eugene Walter, 18, was arrested on a series of rape and sexual abuse charges.
Principal Mark Pinder said the rapes happened between September and December 2012 while Walter was still a student at the school.
Investigators said a 16-year-old girl came forward in February and told police about the assault. Detectives then found the three additional victims. All the girls are younger than 18, police said.
Pinder said they are investigating if any of the alleged assaults happened on school grounds.
"We are providing this information to you at the earliest possible time," the letter to parents said. "We were asked by Milwaukie Police to keep this matter confidential during the investigation leading to the arrest."
"You're talking about the crime of rape, which is just horrific," Pinder told KATU. "Stuff that goes with that crime - the guilt, the shame - is just terrible. We need to support these victims."
Walter is currently being held in jail on $250,000 bail.
Police think there may be more victims who they haven't heard from yet because Walter listed four different high schools on his Facebook page, including David Douglas. He also posted, weeks before his indictment and arrest, that he didn't commit those crimes.
"Walter is well-known to travel throughout the Portland metropolitan area. He's known to have been couch-surfing in Beaverton, in Portland, in Milwaukie, Clackamas County," said Ulli Neitch of the Milwaukie Police Department.
Since leaving Milwaukie HS, Pinder said Walter enrolled at New Urban High School, a program that allows students to do most of their coursework online. He has not been enrolled at MHS this school year and Pinder said he rarely attended last year.
"As appropriate, please review and discuss this issue with your children," Pinder wrote in his letter. "Since you know your children best, you know they may react in a variety of ways. Some may show anger, fear, or disbelief. All reactions are normal in dealing with difficult news."
KATU was able to talk to one of Walter's alleged victims Friday night and the father of a second alleged victim. Neither would do an interview, but both said they want Walter held responsible for what he's done and more victims coming forward to police will help prosecutors do that.
Police say if you have information about the case you can contact Detective Kevin Krebs at (503) 786-7640 or email firstname.lastname@example.org.
