Over the past two years, a man approached women as they left bars in Denver’s Lower Downtown and offered them rides home in his Audi.

But in the case of at least four women, the man raped them in the back of his car before taking them home, police allege.

Denver police have arrested Byron Whitehorn, 50, in those cases, and he has been charged with sexually assaulting four women over the span of more than a year, according to a news release from the Denver Police Department and the Denver District Attorney’s Office.

And police believe there may be more victims.

Police allege Whitehorn picked up the women outside the following LoDo bars on these days:

April 9, 2017 — Lodo’s Bar & Grill, 1946 Market St.

— Lodo’s Bar & Grill, 1946 Market St. Oct. 14, 2017 — Jackson’s Lodo, 1520 20th St.

— Jackson’s Lodo, 1520 20th St. Jan. 28, 2018 — Lodo’s Bar & Grill 1946 Market St.

— Lodo’s Bar & Grill 1946 Market St. Dec. 14, 2018 – The Ginn Mill, 2041 Larimer St.

An arrest warrant affidavit released by the Denver District Attorney’s Office details how detectives solved the case.

On the night of Dec. 14, a woman went to the Ginn Mill bar with her roommate. At about 12:45 a.m. the next day, she told her friend she had too much to drink and wanted to go home. She told police that she called an Uber and was walking outside when a man approached her and offered to drive her home. He took her phone and canceled the Uber ride.

She next recalled awakening in a man’s car as she was being raped, according to the affidavit. She later told police, it was an “out of body experience.”

The man then drove the woman to her Lakewood apartment. When they arrived, the assailant took her phone, recorded his first name, Byron, and entered his phone number and said, “Let’s do this again.”

The woman called 911 and went to Denver Health Medical Center for a rape examination. Detectives soon learned that her attacker’s DNA matched the DNA of a suspect who had raped three women dating back to April 2017 after meeting the women in LoDo bars.

Each of the women had described similar scenarios in which a man approached them in or near bars when they were highly intoxicated. They each awoke while being sexually assaulted.

When a detective called Whitehorn using the phone number he allegedly entered in the fourth victim’s phone, Whitehorn said he didn’t know who the woman was. He told police he often went to LoDo with friends to find women to make out with. He denied raping anyone, according to the affidavit.

A forensic artist created a drawing based on this fourth alleged victim’s description that closely resembled photographs of Whitehorn on his Facebook page. Detectives spoke with the three earlier rape victims, and two recalled that the suspect drove a white sedan and a third said his car had tan-colored cloth seats. Whitehorn owned a white 2005 Audi sedan with tan, cloth seats.

A Denver detective obtained a warrant to obtain Whitehorn’s saliva, and crime lab analysts took his DNA on Jan. 4. The DNA matched the suspect in each of the rape cases, according to the affidavit.

Whitehorn does not have any significant prior criminal history, court records show. He remains in custody and is next set to appear in court on Feb. 26 for a preliminary hearing.

Anyone with information about Whitehorn, or who believes they may be a victim of a similar sexual assault, is asked to call 720-913-2000.
