Tina says her son, David, who goes by the name 2B, was a rising star musician with a record deal, but now, he’s living on the streets.

“It started off out in the nightlife; everybody’s giving him free drinks,” Tina says, adding that it soon escalated to 2B smoking weed and taking pills. “It destroyed him. He quit the band in 2004. By 2015, he was doing heroin. Now, 2B is a homeless heroin addict.”

She says her son’s issues consume her and that she often gives him money or lets him stay at her house because she doesn’t want to see him panhandling. “My son’s destroying his life with drugs, and he’s destroying my life, too,” says Tina, adding that she’s tried everything she can to help her son. “It’s hard for me to believe that when I see homeless people, my son’s one.”

2B’s girlfriend and mother of his 15-month-old son, Stephanie, says that she kicked 2B out of their house because he was too dangerous, but says she still worries about him.

“When I don’t see 2B for a few days, I start to worry. In the past four weeks, I went out four-to-five days a week looking for him,” she says, adding that she dresses like a homeless person to blend in. “I would find 2B about once a week.”
