The idea first came to Donna Alexander at the age of 16 and she grew up in South Chicago in the late 1990s: and if all inmates jailed for injuring people and broken things could make their anger go elsewhere? She had witnessed domestic violence and cut tires and holes in the walls of her own neighborhood. She had known people who had gone to prison for that. And so, after moving to Dallas and graduating, he thought he could offer an alternative. She called it "the room of anger," a business where angry people of all sorts could break glass, television, and computers with baseball bats, tire sticks, and golf clubs. It was one of the first companies of its kind. "Donna's thing was, instead of hurting people, why not leave it on things so that life would not be lost, to keep people out of jail?", Recently declared her sister, Lauren Armor at the Chicago Tribune. "A therapeutic way to attract anger and relieve stress." That's part of the reason why Alexander's death in September was so tragic, Armor said. His ex-boyfriend is now accused of beating Alexander at home. Nathaniel Mitchell, 34, was charged on Tuesday with the death of Alexander after the police declared that he had brought her home to Dallas by the window of her room in the middle of the night and l & rsquo; Had hit the head with an unknown object on September 21, reported CBS DFW. His two children were inside the house at the time. Mitchell was initially charged with aggravated assault before prosecutors turn charges into murder after Alexander's death at the hospital three days after the attack. She was 36 years old. At a vigil celebrating his life a few days after his death, his father, Donald Alexander, said that she had spent much of his life advocating against domestic violence, reported the Dallas Morning News . "At 14, she knew what she wanted to do," he said. "She was really adamant about domestic violence and was working to do something for the community." Donna Alexander moved to Dallas in 2002 to study graphic design and multimedia before landing a marketing job. But the idea she had as a teenager was never far from her mind: in 2008, she decided to finally put it in motion, as she told the New York Times in a 2016 interview. She fills her garbage garage left on the sidewalk, and then opened it to his friends and co – workers who needed a release. For $ 5, they could crush the objects as they please. And when the news spread, they kept coming back. "I started having strangers at my door asking me if my house was the perfect place to break things," she told The Times. "When that happened, I knew I had a business." She officially opened it in 2011 in a 1,000-square-foot warehouse in downtown Dallas. The room of anger, as it was called, was cluttered with furniture, computers, printers, glasses, bottles and dishes. She did not allow machetes, knives and ammunition and asked everyone to wear safety glasses, a helmet and a suit. But otherwise, there were few rules. Upon request, she could even create the scene that her clients wanted to destroy. It could create a fake kitchen, a retail store or an office – even the "Office Space" movie set. "I thought the world needed something like that," she said in an interview with YouTube in a 2012 business battery pack called "Business Battery Pack." "You see so many crimes and tragedies around the world, and I thought that if there was a room of anger somewhere, we could have prevented that or help that person. [The idea] continued to grow in me until I finally got up and did it. In 2018, his company – among a handful of similar operations in the United States and Canada – had attracted national and international attention. She told The Times that she has received about 2,500 requests from entrepreneurs looking to create their own version since they opened. Constant curiosity and publicity helped: The Anger Room was featured in an episode of "The Real Housewives of Dallas" and Ozzy Osbourne visited an A & E segment aired in November 2017. This month, there, she filmed a Facebook Live video of herself. deploring the uncertainty of violence, reported the Morning News. "We can neither help nor control the inevitable. We can not stop the violence, "she said. "It's like a lottery. You will end up dying – and at a time when you may not want to go. It's unclear when Alexander started dating Mitchell or when their relationship ended. Armor told WFAA, an ABC subsidiary in Dallas, that she had written about the toxic relationship in her journal. Before she died, she told the chain that he had been evicted from her home. He returned on September 21st, knocking on the door. According to a police affidavit quoted in the Morning News, Mitchell allegedly took Alexander to the Baylor University Medical Center's emergency center in Dallas early in the morning, informing hospital staff that he was not in the hospital. Alexander had hit her head when she had slipped into the bathroom shower. But the hospital staff was suspicious. They thought that Alexander's injuries were "inconsistent" with a simple shower slip and quickly alerted the police, according to the affidavit. At Alexander's home, the investigators found a broken window in the bedroom with speckled blood on the blinds and window sill. They found blood in the bathtub and shower, as well as on the bathroom floor and bedroom, and found bloody towels in the closet. Police arrested Mitchell while he was still in the hospital. He remains imprisoned on bail of $ 250,000 at Tarrant County Penitentiary. It was not possible to immediately locate a defense lawyer, and it is not clear whether he entered a plea. Before his death, Alexander was looking to expand the Anger Room in Las Vegas and Kentucky. But without Alexander, the room of anger is no longer in business, at least for the moment. Alexander's death had been "overwhelming," his sister wrote in a post on the company's Facebook page. "No matter how much she tried to get out of it, he always ended up in his life," Armor told the Tribune. .
