Former detention officer, Army Reservist, accused of sexually assaulting inmate

Sean Allen, 30

A former Campbell County Sheriff’s Office (CCSO) detention officer has been bound over to District Court on charges alleging he sexually assaulted a female inmate while she was in jail.

Sean Allen, 30, is charged with one count of third-degree and two counts of second-degree sexual assault stemming from several incidents that reportedly began in May and ended in July of 2021, according to an affidavit of probable cause filed in the case.

Investigators with the Wyoming Division of Criminal Investigation (DCI) were initially notified of the alleged incidents after CCSO leadership received a report from a female inmate in July who claimed that a detention officer, Allen, had engaged in sexual intercourse with another inmate.

The report alleged that Allen and the inmate were openly flirtatious with each other, often spending time together alone in the inmate’s cell, according to the affidavit, which adds that CCSO leadership reportedly substantiated enough of the claims through surveillance footage to forward the case on to DCI for investigation.

When interviewed, the complainant told agents that Allen and the inmate had “hooked up” and that it was “obvious” they had engaged in sexual activity based on the noises, like heavy breathing and moaning, that she and the other inmates often heard coming from the cell when Allen and the inmate were alone, per the affidavit.

The complainant also told agents that the female inmate had recently mentioned that she was “working on him” and that Allen would sometimes bring the inmate items like soap and toothpaste.

Other inmates, when interviewed, told agents that they thought it was strange how many times Allen was seen going in and out of the female inmate’s cell given how rare it was for him to enter any of their cells, per the affidavit.

Communication logs for the female inmate were also reviewed, where agents reportedly found a message from the inmate to an ex-boyfriend outside the jail.

“I can officially go and fully give myself to a real man who has his s—t together, who’s in the Army, someone who’s never done drugs before, someone who likes me a lot and would never do anything to hurt me and he’d give everything just to see me smile,” the inmate wrote, according to the affidavit.

Allen, at the time of the alleged incident, was an Army reservist, per the affidavit.

When the agents interviewed the inmate, she told them that Allen first snuck into her cell in May this year, where he reportedly woke her up at 4 a.m. by kissing her on the mouth, told her that he was working alone and that no one would know where he was, per the affidavit.

During that incident, Allen reportedly put his hand down her jumpsuit and touched her, the affidavit states, which adds that he reportedly made her feel that if she didn’t do what he wanted then she would be in trouble.

From then on, Allen would repeatedly come into the female’s cell to kiss her, sometimes touching her or putting his hand around her throat, the affidavit states, despite the female being moved around multiple times from cell block to cell block.

The female also told agents that she was glad nothing happened in one of the blocks because the detention center cameras could see into the block, which meant that Allen wouldn’t come in to kiss her.

Later, during a second interview, the female told agents that on one of those occasions when Allen came to her cell they engaged in sexual intercourse, and during another that she had performed fellatio on him, according to the affidavit.

When she spoke with him about what had allegedly transpired between them, Allen reportedly told her that he like the thrill and that no one would find out about the incident if she “kept her pretty little mouth shut,” per the affidavit.

During his interview, Allen told agents that he had no romantic interest in the female inmate and that he had only gone into her room because it was something that he knew he wasn’t supposed to do.

Sneaking into her room, he told them, gave him an adrenaline rush and he thought the female inmate liked it, according to the affidavit.

Allen also said that he would use a key to enter the female’s cell, rather than open the door using the electronic controls, because it was quieter and less likely to wake the other inmates, per the affidavit.

Jail door logs and surveillance cameras reportedly showed Allen using a jail key to open a door to the cell assigned to the female at 4 a.m. on May 23, where he remained for a couple of minutes before exiting and securing the door, the affidavit states.

Surveillance also allegedly showed Allen entering the female’s cell after she showered on June 30, while she was only wearing a towel, and closing the door partially. A few minutes later, Allen was seen leaving the cell, and the female emerged shortly after, this time wearing a yellow jumpsuit, the affidavit states.

Between May and July 2021, surveillance reportedly showed Allen entering the female’s cell multiple times a day, though he didn’t enter any other inmate’s cell, per the affidavit.

Second-degree sexual assault is punishable by not less than two years in prison up to 20 years and third-degree sexual assault is punishable by not more than 15 years.
