What happened during the days leading up to Jan. 31, when Bobbi Kristina Brown was found unresponsive in her bathtub, continues to remain unclear several months later. The truth about what happened on that day that led her to be placed in a medically induced coma for nearly seven months before she passed on July 26 may never completely come out, but some dark details have just been released, and what her ex-roommate had to say about her comes as a shock to most.

Danyela Bradley lived with Brown and was in the home when she was found, and now court papers from a recent taped deposition with Bradley reveal some interesting details about Brown's drug use.

"She smoked marijuana, she probably smoked crack often and also did heroin," Bradley told the lawyers in the deposition obtained by Radar. "When she would do the heroin she'd just be very sleepy, nod off, and very less talkative, kind of keep to herself. When she would smoke crack, she would just be not even talkative. She'd just be keeping to herself as well."

She went on to explain that Brown would only do crack "like once or twice every two weeks" and that she'd never actually witnessed her doing any drugs except marijuana, but she "was aware.: When I first lived with her, I didn't know she actually had a problem with it," she added. "Until I had lived with her afterwards for a couple of weeks...and after a few weeks she just really didn't hide it."

As for Brown's relationship with her boyfriend Nick Gordon, who is being accused of injecting Brown with a "toxic cocktail" that eventually led to her death, "They had a very happy, loving relationship," Bradley explained, according to People. She later said that Gordon also smoked crack and that he did it "more than [Brown]."

Gordon continues to face murder charges, but this new information might shed some new light on what really led to the death of Whitney Houston and Bobby Brown's daughter. These new allegations are being brought on by a lawsuit from Russell J. Eckerman, who was injured in a car crash involving Brown and Bradley. It was Eckerman's attorneys who asked Bradley all of these questions, trying to find out what really happened on that day in January.

Eckerman's attorneys are trying to figure out exactly what drugs Brown had been doing and how much of each she had taken. They have requested a full toxicology report, outlining 15 different substances including amphetamines, methadone and cocaine.
