Joe Tumpkin’s former girlfriend told Broomfield police that the former University of Colorado assistant coach assaulted her more than 100 times over the course of 21 months, according to court records obtained Thursday.

Tumpkin, 45, appeared in court Thursday in Broomfield to be advised of five counts of felony second-degree assault. He was free on bond, and was set for a preliminary hearing on March 23.

Tumpkin did not comment on the allegations during or after Thursday’s hearing at the Broomfield Combined Courts.

According to an arrest affidavit, Tumpkin’s ex-girlfriend told investigators that he assaulted her more than 100 times between February 2015 and November 2016.

The woman told police on Dec. 19 that she began dating Tumpkin while she was living in Michigan and Tumpkin coached at Central Michigan. When Tumpkin was hired as the safeties coach at CU and moved to Colorado, she said she flew out to visit Tumpkin every 10 days or so.

She told police the first incident happened on Feb. 26, 2015, when she said he assaulted her after she found him at a bar with another woman and accused him of cheating on her, according to the affidavit. She told police Tumpkin choked her, pushed her into walls and head-butted her.

According to the affidavit, despite seeking couples counseling and discussing marriage, the assaults continued.

Broomfield police Detective Dale Hammell asked the woman “to tell me how many times she was physically assaulted by Joe, and she said in excess of 100 times,” according to the affidavit. “She told me she was choked in excess of 100 times.”

She told police that during one incident, Tumpkin picked her up over his head and appeared to be ready to slam her to the floor before he ultimately put her down.

Broomfield police responded to Tumpkin’s residence on March 12 after a neighbor called and said she heard what sounded like domestic violence. The woman said she heard a man screaming, “I will (expletive) kill you,” and the female screaming in pain.

Tumpkin’s ex-girlfriend told the officers who arrived that night that they were having consensual sex, but later told police she was lying at the time and that they had been fighting.

The property managers at Tumpkin’s residence also said they had received complaints from other neighbors about what sounded like domestic violence. There were texts from Tumpkin to the woman apologizing, but never saying what he was apologizing for, according to the affidavit.

The day after making this report to police, the woman applied for a temporary restraining order, which later made permanent.

The woman had called CU coach Mike MacIntyre before going to police, hoping the university would get Tumpkin help, but ultimately the school stopped contacting the woman, according to a story published by Sports Illustrated.

Tumpkin went on to coach in the Buffs’ Dec. 29 bowl appearance despite school officials knowing of the allegations against him.

Tumpkin was told by CU to resign on Jan. 27 and he was arrested on Feb. 1.
