TMZ first reported that Max Lomas, 29, was found dead in Mississippi on Wednesday. People magazine later confirmed the news, citing medical examiner's documents that said a friend found Lomas in a bathroom "with a syringe nearby." Results from a toxicology test should be available in six weeks, People reported.
Lomas reportedly was with Whitney Houston's daughter and her boyfriend Nick Gordon in her final days conscious in early 2015 in their Roswell, Georgia, home. She never regained consciousness and officially died a few months later.

Lomas told People in 2016 that he had lived with them on and off for weeks and noted a lot of drugs, partying and fights.
"We were all pretty bad into drugs," Lomas said.
Gordon lost a civil suit and was accused of being "legally responsible" for Bobbi Kristina's death, something he has denied. The court has entered a judgment of $36 million against Gordon.
