A former D.C. police officer sexually assaulted women he met on dating platforms in multiple cases across the region, authorities said Monday, adding that police are looking for more potential victims.
Timothy Valentin, 30, faces more than a dozen charges in Maryland and Virginia after police say he took women on dates — sometimes using an alias — then drugged and assaulted them while they were unconscious. He is suspected in assaults in Alexandria, Virginia, as well as in Montgomery and Prince George’s counties in Maryland.
Valentin, of Fort Washington, Maryland, is in custody in Alexandria, where he has been since December on charges of rape, abduction with intent to defile and other counts for an alleged assault in that community. He was indicted Monday on additional charges of rape and abduction related to three more alleged victims, whom Valentin also allegedly filmed, Alexandria and Prince George’s County officials said Monday at a joint news conference.
In all, Valentin is being accused of assaulting at least 11 women between 2024 and 2025, though police urged other potential victims to contact them.
“I want to acknowledge the enormity of this moment,” said Alexandria Police Chief Tarrick McGuire at the Monday news conference. “These cases underscore that sexual violence is a deep violation of a person’s human rights.”
News of Valentin’s arrest came the same day the Atlantic published an investigation detailing assault allegations against him. The report, citing officials familiar with the investigation and suggesting that there are dozens more victims, said Valentin recorded the alleged assaults.
An attorney for Valentin did not immediately respond to a request for comment. Efforts to contact relatives of Valentin on Monday were unsuccessful.
Valentin worked as a D.C. police officer between 2017 and 2022, when he resigned from the force, a police spokesman said. The spokesman said his assignments were in patrol and declined to comment on whether D.C. police are investigating him for any sex-related crime — either during his time on the force or after — or whether he was the subject of an internal investigation in the department before he resigned. Valentin was awarded the Ribbon of Valor in 2021, along with dozens of other D.C. police officers, though a police spokesman declined to provide details.
Alexandria Commonwealth’s Attorney Bryan Porter said Monday there was no evidence to suggest that Valentin committed any of the alleged crimes while working for D.C. police.
Valentin worked as a contractual fraud and enforcement investigator for the Maryland Insurance Administration, an independent state regulatory agency, from May 7, 2025, to Dec. 31, 2025, according to spokesman Craig Ey.
Police began investigating Valentin for the alleged assaults in spring 2025.
McGuire, the police chief in Alexandria, said a woman reported a sexual assault to D.C. police in the spring of that year. D.C. police determined that the incident occurred in Alexandria and referred the case to that city’s police department, which took over in August.
Court documents allege that Valentin met up with the woman, whom he first encountered on a dating app, at an Alexandria bar on April 12, 2025. Video of the incident showed Valentine slipping a powdery substance into the woman’s drink while she was in the bathroom, prosecutors alleged in the documents filed in Alexandria Circuit Court. The woman left the bar with Valentin, then blacked out and, later, woke up to realize she was being assaulted, court documents said.
The woman agreed to a sexual assault exam, the documents said. A forensic analysis of her urine tested positive for Bromazolam, a drug similar to Xanax that causes amnesia, sedation and muscle relaxation, according to court documents.
“The victim has never knowingly consumed that drug,” Alexandria prosecutors alleged in the court documents.
After a “lengthy investigation,” Porter said, an Alexandria grand jury indicted Valentin on Dec. 8, 2025.
Three days later, police spotted Valentin traveling through the city and arrested him, Porter said.
Officers recovered a firearm and bags of powdery substances from his vehicle, according to court documents. He told them his encounter with the woman from the alleged April assault was recorded and “all sexual contact was consensual,” the court documents said.
But police found more evidence on his phone, Porter said.
On it were dozens of videos — recorded between May 2024 to November 2025 — of “the defendant having sex or participating in other sexual acts with women who showed signs of significant intoxication or were incapacitated,” prosecutors said.
At least one recording captured parts of Valentin’s encounter with the victim from April 2025, according to court documents, though that video mostly consisted of a black screen with sound. Valentin also allegedly took photos of the women’s driver’s licenses.
On Monday, Porter said, an Alexandria grand jury returned a “superseding indictment” detailing the charges related to three victims.
In the first of those cases, Valentin allegedly sexually assaulted the same woman twice, days apart, in March 2025, Porter said. The second case also occurred in March 2025, Porter said, while the other case occurred in November 2025.
Valentin faces multiple counts that each carry up to life in prison, Porter said. Additional charges could come in the future. He is scheduled to face trial in Alexandria in August.
In Maryland, police said, Valentin sometimes went by “Rico” or “Teo.”
Prince George’s police began investigating Valentin’s alleged crimes in January, after officials in Alexandria alerted them to the six potential victims in that community. Police in Takoma Park — a city in nearby Montgomery County — launched their own investigation a month later.
In one case, Valentin is alleged to have met a victim at Blue Sunday Bar & Grill in Bowie on April 7, 2025. The two then went to the Society Restaurant & Lounge in Silver Spring.
Police said Valentin then took the woman to Takoma Park in the 7600 block of Hammond Avenue, where, they say, he sexually assaulted her.
Takoma Park police said the department is coordinating with the Montgomery County state’s attorney’s office and that criminal charges “are forthcoming.”
