Bobbi Kristina Brown Update: Nick Gordon Posts Cryptic Message Amid Claim He Gave Whitney Houston’s Daughter ‘Toxic’ Cocktail

Bobbi Kristina Brown’s boyfriend Nick Gordon posted a cryptic message on his Twitter account Sunday just a day after he was accused of giving her a "toxic" cocktail the day she was found unconscious in a bathtub at her Atlanta home. The daughter of Bobby Brown and late Whitney Houston died on July 26 at the age of 22 after remaining in an unresponsive state for months in several facilities.

"Can't run from the pain go towards it. Somethings can't be explained what caused it. When I lost you I lost it," Gordon wrote on his Twitter account. In another Twitter post Thursday Gordon remembered his late girlfriend, saying: "When you would do anything in the world to spend 5 min with her again."

Bobbi Kristina Brown's estate accused Gordon of injecting her with "a toxic mixture" before she was found face-down in a bathtub on Jan. 31.

The court documents claimed that Gordon caused the death of Whitney Houston’s daughter because of "a violent altercation . . . after which he placed her in the bathtub unconscious, after he injected her with a toxic mixture."

Earlier this month, reports surfaced that the Fulton County medical examiner knew the cause of Bobbi Kristina Brown's death, but was ordered by a judge to keep the findings sealed. The D.A. feared that seeing the results could "create risk of flight" for defendants in the case.

"The criminal investigation involving possible charges in this case is ongoing, no arrests have been made, and disclosure of the autopsy report and the above-mentioned information at this time would compromise the integrity of the investigation and create a risk of flight in possible defendants, and could pose a danger to witnesses involved in this case," the filing, obtained by WSB-TV, stated.

Bobbi Kristina Brown's family filed a $40 million wrongful death lawsuit against Gordon alleging that he physically abused his girlfriend and also stole her money.
