A Casper Police Department detective described a "definite correlation" between two rapes that allegedly occurred in September and May. In both cases, Jacob Paquette, allegedly held the victims against their will before raping them and he had been in prior dating relationships with them.

Both victims in the separate incidents said Paquette holding them against their will Prosecutors initially charged Paquette, 20,  with four counts of first-degree sexual assault, aggravated assault and battery, strangulation of a household member, felonious restraint and sexual exploitation of children last month.

A fifth sexual assault charge was added after initial court filings.

The charges were filed in connection to the events which allegedly occurred in September and May.

The case was bound over to Natrona County District Court Tuesday.

According to an arrest affidavit, the alleged victim and Paquette were living together at the time of the incident. She was leaving her job when Paquette pulled up in a separate vehicle, which surprised the victim because Paquette was supposed to be working.

The alleged victim went home briefly before she attempted to leave, but Paquette sent her a text message asking her to come inside and talk. She went inside.

When the alleged victim tried to leave, Paquette grabbed her and forced her onto a couch. Paquette later shoved her onto a bed in a separate room. She screamed but Paquette repeatedly covered her mouth and nose with his hands, eventually grabbing a pillow and holding it over her face.

The alleged victim managed to get to a bathroom and lock herself in. When she came out, Paquette held her down and raped her, according to the arrest affidavit.

It happened two more times. At one point, Paquette poked the alleged victim's back with a knife.

In September, Casper police began investigating a reported sexual assault. The victim in that case  recalled being thrown before Paquette put a dresser in front of a door so she couldn't escape. Then he raped her, court documents say.

When the second case was reported, police saw a "definite correlation" between the two incidents, Casper Police Sergeant Mitch Baker said.

Baker, who was a detective at the time of the September incident, appeared in Natrona County Circuit Court Tuesday and said when police began investigating the incident, the victim provided pants that were ripped below the zipper.

The alleged victim told police that she tried to call relatives for help but Paquette took her phone from her.

Baker said he had difficulty reaching Paquette to carry out the investigation.

Baker briefly called Paquette who said he was familiar with the alleged events. They never spoke again. After three weeks, Baker forwarded the case to the Natrona County District Attorney's Office.

At some point, Baker said, Paquette was living around Big Piney in Sublette County.

An arraignment date, where Paquette will plead to the charges in Natrona County District Court, has not yet been scheduled.
