MOORESTOWN, New Jersey (AP) — A series of online messages from a long-ago schoolmate has a Gettysburg College graduate trying again to get authorities to make an arrest in her 2013 sexual assault. Shannon Keeler says she had fended off an upperclassman at a fraternity party that night only to have him follow her home and rape her. Prosecutors declined to prosecute the case at the time even though she had a hospital rape exam, text messages and witness statements. Advocates say prosecutors must do more to make arrests in campus sex assaults. The 26-year-old Keeler hopes the latest messages from her alleged attacker will finally be enough.
