The estranged boyfriend of a well-known entrepreneur who advocated against domestic violence is charged with the woman's murder.

Donna Alexander created “The Anger Room” for stress relief, which took off and made national headlines. She died in the hospital this week after Grand Prairie police say her estranged boyfriend, Nathaniel Mitchell, severely beat her. He is charged with murder.

Delores Hodge shared a birthday with her friend, Donna Alexander. They called each other their twin.

Alexander was taken off of life support this week after police say she was assaulted last Friday at her Grand Prairie home by her live-in boyfriend, 34-year-old Nathaniel Mitchell.

"She was sweet. So sweet. So soft-spoken,” Delores said. “My last text message from her, she said ‘I love you.’"

FOX 4 talked to Donna Alexander last year when she opened her new business: The Anger Room. It was a way for people to blow off steam by smashing things. Her business made national headlines. She even planned to expand.


Grand Prairie Police say were called to Baylor University Medical Center in Dallas Friday morning. Alexander was in the E-R. She had severe head injuries.

Detectives say Nathaniel Mitchell, who was there at the hospital with her, gave inconsistent statements. Police arrested him on the spot for outstanding warrants. And within a few hours, they charged him with aggravated assault on Alexander. When she died, he was charged with murder.

Alexander leaves behind a son and daughter and a legacy to bring awareness to the very issue that may have taken her life.

“For it to be that she expired the same way for something that she was advocating against…” Delores said. “You think about what makes your mind say, ‘Wow, this thing is so real.’ You just never know."

There is a vigil planned in Dallas Monday evening at 6 p.m. at Cole Park.
