A Denver man accused of offering rides to other men after they left bars and then sexually assaulting them has been charged in connection with five assaults between 2013 and 2018, according to arrest documents.

Tobias Favela, 50, was arrested Friday and charged Tuesday with six felony counts of sexual assault, according to the Denver District Attorney’s Office.

Police tied five incidents — taking place Nov. 2, 2013, Feb. 27, 2016, March 19, 2018, April 1, 2018, and Sept. 22, 2018 — to Favela through DNA results, suspect descriptions including the suspect’s “high-pitched voice,” and a phone number, according to an arrest affidavit.

In each of the five cases, men who had left bars or nightclubs near downtown Denver after they were separated from the people they were with had reported finding themselves in the suspect’s vehicle, thinking they were being taken home, police said. In one case, a man had ordered an Uber and thought he was being transported to his home, and in another, the man thought they were stopping at a friend’s house to get some money to pay for the ride.

The men reported periods of blackouts and finding a man on top of them who was sexually assaulting them before they somehow managed to get back home, according to the affidavit.

In one of the assaults, a victim reported a phone number to police — he found a missed call on his phone, and the number was later tied to the suspect. The victims described the suspect’s “high-pitched” voice to police, which investigators compared to body-worn camera footage from an earlier traffic stop of the suspect as well as his phone and other 911 calls he previously had made, according to the affidavit.

Police had matched the DNA samples in four of the cases to one suspect but had not yet identified him, according to the affidavit. They connected the fifth case to the others through DNA on May 30. After identifying the suspect, who lived half a mile from 26th and Welton streets, police obtained a saliva sample from him on Friday which matched the other DNA samples, the affidavit stated.

Favela was arrested and is being held in the Downtown Detention Center on a $50,000 bond, jail records show.

The DA’s office and the Denver Police Department believe there may be other victims and ask that anyone else who may not have reported their assaults contact the Denver Police Department’s Sex Crime Unit at 720-913-6040 or report online at seekthenspeak.org. Reports can remain anonymous.
