Nick Gordon’s attempt to get a judge to stay a civil lawsuit against him has hit a major roadblock after Bobbi Kristina Brown’s estate filed documents in Fulton County court alleging he injected her with a toxic mixture that led to her death.

The estate filed the $40 million civil lawsuit against Gordon in June. It was amended in August, just weeks after Bobbi’s July 26th death.

WSBTV reports that the motion filed by Brown’s estate says Gordon’s request should be denied, citing that Gordon “has no problem giving an interview to Dr. Phil but asks this court to relieve him of his legal responsibility.”

The suit further alleges that Gordon injected Bobbi followING “a violent altercation with Defendant after which he placed her in the bathtub unconscious, after he injected her with a toxic mixture.”

Bobbi, 22, the only child of Whitney Houston and Bobby Brown, was found by Gordon and a family friend in her Roswell, Georgia home on January 31, 2015. She was face down, unconscious, submerged in water in the bathtub.

After being rushed to the hospital she was placed in a medically induced coma. Her condition never improved and the Brown and Houston families made the decision to take her off of life support and move her to hospice care, where she passed away.

Gordon is a person of interest in a criminal investigation into her death.

The Fulton County district attorney has requested that the results of Bobbi’s autopsy report not be released yet because of possible danger to witnesses.
