By Lori EhdeActing on a tip from an unnamed informant, Rock County deputies arrested three local young people last week for possession of methamphetamine.According to documents filed Monday in Rock County District Court, 22-year-old Jeremy Alan Wallenberg, 23-year-old Shaun Robert Edberg and 18-year-old Ashley Wynn Mortimer were arrested Thursday, Sept. 16.The arrests were the result of a search warrant executed on a trailer home on West Mead Court after someone tipped off police about drug use there.At about 9:30 a.m. Thursday, Sheriff Mike Winkels and five deputies searched the trailer, rented by Wallenberg and Mortimer. Edberg said he’s also been staying at the trailer.According to the complaint, law enforcement found all three in the trailer, in addition to Michael Reverts, who doesn’t face any charges at this time.All were handcuffed during the search as a precaution, but no weapons were found in the home.Small amounts of powder and rock meth were found around the trailer, and Wallenberg and Edberg admitted to smoking marijuana and meth the night before.Wallenberg, Mortimer and Edberg were transported to the Nobles County Jail and now face charges of fourth-degree controlled substance crime.Investigator Jeff Wieneke said it’s not been established whether the three were dealing drugs or if they had connections to the Steven Mauch case in Nobles County."That part is still being investigated," he said.
