“I heard Michael say, ‘I have a right to not let you in my house,'” said his fiancee, Kimberly. However, her story differs from deputies’ telling of what happened next.

The sheriff’s department says Thomas struggled with deputies, reaching down to try to take one of their guns, prompting one of the deputies to shoot.

Kimberly says Thomas was only trying to turn away from deputies.

The family’s attorney, Bradley Gage, said Thomas did not have a weapon and was not hurting his fiancee. According to the family, the two were only having a verbal argument and there was no reason for Thomas to be detained in the first place.

“That’s exactly why we have a fourth amendment,” Gage said. “It’s to avoid the kinds of illegal searches and seizures where the police come into people’s homes and harm them or, here, kill them.”

The shooting occurred at 5:23 a.m. in the 600 block of West Avenue H12, the sheriff’s department reports.
