A Longmont man faces bias-motivated charges stemming from allegations that he screamed racist slurs at a Hispanic family using the pool at his apartment complex and possibly armed himself with a pistol wrapped in a towel.

An arrest warrant affidavit alleges Kevin Edward McMahon, 53, was using the pool at the Fox Ridge Apartments on June 13 and started screaming “wetback” at a Hispanic family and saying, “When Trump builds the wall, they are gonna need to know how to swim back home.”

He also reportedly asked one of the men in the family if he urinated outside “like an animal.”

McMahon faces two counts of bias-motivated crime, one count of disorderly conduct and 10 counts of felony menacing.

Police allege McMahon also announced that he was going back to his apartment to retrieve a firearm, and then returned with what appeared to be a pistol wrapped in a towel, which he placed on a table.

McMahon, who could not be reached for comment late Saturday, was briefly in custody at the Boulder County Jail on Friday, but was not in custody Saturday evening. He reportedly refused to turn himself in on June 25 when Longmont police informed him they had a warrant for his arrest, according to the affidavit.

A witness at the pool told police that she thought she saw a pistol case wrapped in the towel after McMahon announced that he was “going to get his piece” and briefly left the pool area. She described McMahon as being extremely drunk, according to the affidavit.

The witness told police that a maintenance worker at the apartment complex came to the pool and made McMahon take the presumed gun back to his apartment, but that he returned a few minutes later.

The maintenance worker, who told police that he is friends with McMahon, said that he was meeting his friend after work and heard McMahon antagonizing the Hispanic family and making motions as if he were armed. McMahon reportedly also made racist comments regarding the maintenance worker’s Native American heritage, according to the affidavit.

The worker later told police he didn’t think McMahon was actually armed. But an officer at the scene noted that the worker appeared to be protecting his friend, by saying he “is a good guy, but he gets belligerent when he drinks, and he drinks all the time,” according to the affidavit.

After police removed McMahon from the pool area, he reportedly told officers that he began to “voice his opinions” after becoming upset when one of the Hispanic men bumped into a woman in the pool and didn’t apologize. He said that he probably said some things that he shouldn’t have, but was upset because the apartment complex and pool area “used to be a nice place.”

When police asked McMahon, who had been swimming with his granddaughter, if he said he was going to get a gun, he told them that he actually said he might have said that he was “going to my apartment to get some more rum, and rum sounds like gun, so I could see how they might think that,” according to the affidavit.

Two witnesses told police that the Hispanic family doesn’t live at the apartment complex, but they also said that McMahon was drunk and acting belligerently. One of the witnesses also said that he appeared to have his hand under the towel as if he had a weapon.

But a little more than a week later, police were able to find the Hispanic family, and confirmed that they do, in fact, live at the apartment complex. A man in the family’s apartment told police via an interpreter that his kids had splashed a woman in the pool, and that is when McMahon became angry.

The man told police that because he does not speak English well, he didn’t know what McMahon was saying. He told officers he tried to apologize, but that McMahon was not placated, and he was afraid of McMahon because of his tone and gestures, according to the affidavit.

McMahon does not appear to have a court date set, according to online court records. There is also no indication that he has a criminal record in Colorado.

A call to Fox Ridge Apartments was not immediately returned on Saturday afternoon.
