A Denver police officer accused of sexual assault was arrested Thursday afternoon on suspicion of tampering with the evidence from a different assault by two Denver sheriff’s deputies.

Henri Soni, who was already under investigation for allegedly sexually assaulting a woman he had met while responding to a noise complaint, now faces four additional felony charges after he allegedly tried to cover up an unrelated assault by an off-duty police officer on a man in a wheelchair after Soni failed to write up a report and communicated with the alleged assailants.

Two longtime Denver Sheriff’s Department deputies — Sgt. Carla Gentempo and Deputy Jason Gentempo — were also arrested Thursday in connection with a third-degree assault of an at-risk adult. A review of arrest records revealed that their assault took place on the same day as Soni’s cover-up and also involved a victim in a wheelchair.

Authorities confirmed the two incidents were connected when asked by The Denver Gazette Friday afternoon.

The assault took place on Oct. 17 when a caller reported he had been punched and knocked to the ground by an off-duty Denver police officer, according to an affidavit for Soni’s arrest. Soni arrived at the scene to investigate the call just before 9 p.m. that night and cleared it about 40 minutes later.

While examining Soni’s body-worn camera footage from his response, investigators saw him talking to the reporting party on the patio of his apartment, where the caller showed Soni surveillance video of a man and woman assaulting him with punches and kicks, according to the release. Soni recorded the video with his phone and gave the caller his card with the case number written on it.

The caller identified the assailants as a husband and wife, according to the affidavit.

In a separate affidavit for Jason Gentempo’s arrest, investigators said the victim told them that he had arranged to meet with the two at his apartment. The victim’s relation to the two deputies and Soni is either redacted or not mentioned in any of the records provided by police.

That victim told police how, when the two arrived, they punched and stomped on him before knocking him out of his wheelchair and leaving, according to Gentempo’s affidavit. He also told police that a car crash left him with a permanent disability a decade ago.

Despite Soni saying that a report had been made in his Computer-Aided Dispatch (CAD) notes, when the officer writing the affidavit went to review the police report in the department’s record management system, he found one had never been written, the investigator said in Soni’s affidavit. The affiant was then assigned to investigate an internal complaint on Nov. 13 that Soni violated department policy by failing to make, file or complete official required reports.

When the affiant went to physically examine Soni’s department-issued iPhone 13 on Nov. 21, he saw it was on airplane mode and unable to receive new calls or texts, according to the affidavit. When the officer took it off airplane mode, he saw multiple text messages, originally sent on Nov. 9, received on the phone.

Those messages were sent by the alleged Oct. 17 assailants, according to the affidavit.

Investigators contacted the victim on Dec. 3, who said that Soni had called him about six hours after the assault — around 3 a.m. the following morning — and said that if he still wanted to report the incident, he’d have to be arrested, according to the affidavit. The victim had an outstanding warrant at the time and did not know if that was what Soni was referring to.

The four charges Soni faces from the incident include attempting to influence a public servant, forgery, tampering with physical evidence and first-degree official misconduct, all of which are felonies, according to the release. He was suspended without pay after his arrest.

In addition to the felonies, Soni was already under investigation for three suspected charges in relation to an alleged sexual assault that took place around Nov. 4 of this year, while Soni was on duty, according to the heavily redacted arrest affidavit for that incident.

The victim of the assault told investigators that she had woken up to Soni knocking on her window around 3 a.m. that morning, and was confused why he was there but let him inside, according to the affidavit. Once in the apartment, Soni removed his ballistic vest, pushed her up against a wall and began kissing her.

The victim said it “felt like too much” and she didn’t want him doing anything to her, but they ended up in the bedroom, according to the affidavit. She did not know the name of the officer but provided investigators a phone number he had given her — the number matched that of Soni’s department-issued phone.

The victim said that she first met Soni while he was responding to a noise complaint in September, and that he began repeatedly calling and texting her after that incident, according to the affidavit. She met up with him four different times: once during the initial call, another when he took her for a ride in his patrol car, a third for another noise complaint and the fourth was when the assault took place.

After she was taken to the hospital the night of the assault, the victim identified Soni’s photograph out of several night shift officers as the man who assaulted her, according to the affidavit. Soni’s patrol vehicle GPS also placed him at the location of the victim’s apartment the night the assault took place.

An examination of Soni’s phone during the investigation found he had texted the victim twice the day before the assault, including around 11 p.m., when he said “oh no you’re sleeping lol,” just four hours before he showed up at her window, according to the release. He then texted her again on Nov. 5, just 17 minutes after he was contacted by internal affairs about the investigation.

“Hey can you call me back it’s important,” Soni’s text read, according to the affidavit. The officer writing the affidavit noted that Soni had not been told who had made the complaint or who was involved when he was contacted.

Investigators also reviewed Soni’s call sheet from that night and found he had been dispatched to a “Nature Unknown” call at 1:56 a.m. that night, but a snapchat video sent by the victim showed him standing in her apartment a minute later and talking into his radio, according to the affidavit. The affiant reviewed other records and found he never responded to the call.

Another party, whose name and affiliation with Soni is redacted in the affidavit but appears to be a fellow officer, told investigators after he and Soni responded to a call about a suicidal person weeks before, Soni said he thought she was attractive and asked if he should text her, according to the affidavit. The officer also told investigators Soni had called him about the assault allegations, and said he had “messed up.”

Soni faces three charges in connection with the assault, including sexual assault, unlawful sexual conduct from a peace officer while on duty and unlawful sexual conduct from a peace officer as a show of authority, according to the release.

The department removed Soni from his assignment on Nov. 5 and ordered him to be at home for an eight-hour shift each day during the work week while they investigated the sexual assault, according to the release. That was before Soni was arrested Thursday afternoon on the felony offenses.

Soni joined the department in November 2024 and was most recently assigned to District Three patrol, according to a Thursday news release from the Denver Police Department. He faces a total of seven charges in connection with two different incidents.

Carla and Jason Gentempo, listed as both boyfriend and girlfriend as well as husband and wife in separate arrest records, are longtime employees of the Denver Sheriff’s Department, according to a separate news release. Carla became a deputy sheriff in 2010 and Jason started with the department in 2005.

Denver police are continuing to investigate the case. After it makes its way through the courts, the department will conduct an administrative review of the incidents in collaboration with the Denver Department of Safety and the Office of the Independent Monitor.

Anyone who has additional information about Soni or may have been a victim of his criminal conduct is asked to contact the Denver Police Department at (720) 913-2000.
