After two years, a Mount Pleasant man accused of sexually assaulting a female Ferris State University student has been brought back to Mecosta County for prosecution. In April, 28-year old Christopher Lauer was sentenced to four to eight years in prison after pleading guilty to one count of felony rape in Pennsylvania. In Mecosta County, he is charged with first-degree criminal sexual conduct for allegedly raping a hearing-impaired female student at Ferris State in 2010. Lauer also is hearing impaired.
