SALT LAKE CITY — Police have arrested a Salt Lake man accused of drugging and sexually assaulting a woman.
Now, investigators are looking for possible additional victims.
"Based on the current investigation, detectives believe there may be other women in our community who have relevant information or who may have had similar experiences," Salt Lake police said.
A woman met up with John Riley Harper, 45, on June 18 near 700 South and 400 East. She later told police that "John gave her a few glasses of red and white wine and she did not see him pour them," according to a police booking affidavit.
"The victim reported that she did not consume enough alcohol to black out or have memory loss. The victim reported that she had no memory after consuming the glasses of wine until the morning of June 19," the affidavit states.
When she woke up on the ground of the trailer without any clothes on, the woman believed she had been sexually assaulted. She went to a local hospital for a sexual assault examination.
"The victim reported, multiple times, that she did not consent to anything sexual with John and had no sexual attraction to him and never would do anything with him. The victim's toxicology report from the hospital showed cocaine and ecstasy in her system, which she stated she had no memory of taking and would not have voluntarily used those substances on a weeknight around John. The victim stated that she had heard from others that John utilizes date rape drugs and sexually assaults individuals," the affidavit alleges.
Police were contacted and a search warrant was served on his trailer. They found empty wine bottles, "multiple capsules," and a white substance that tested positive for cocaine, the arrest report says.
Detectives, along with officers from the Violent Crimes Apprehension Team, took Harper into custody and booked him into the Salt Lake County Jail for investigation of rape, surreptitious administering of a drug and two counts of drug possession.
"Additionally, multiple other victims have reported being drugged without their consent and sexually assaulted by John and their cases are being investigated. There are a multitude of ongoing investigations into the same behavior and additional rape charges to multiple individuals over the course of years," the affidavit states.
Anyone with additional information about the case or anyone who believes they may have had a similar encounter is asked to call Salt Lake police at 801-799-3000
