"It's devastating because one day I'm going to have to eventually tell him [her son]," Bell said.
Before the tragic discovery, Bell said her daughter was having confrontations with someone who lives in the unit where, police say, she was eventually killed.
"I've spoke to her about it. I said, 'I don't think it's a good idea. I think you all should end that. It's toxic. You're still young. You have your life ahead of you,'" Bell said. "I'm sorry that I wasn't there to protect you, and I couldn't hold you and tell you, 'I love you!'"
