*Nick Gordon took to Twitter on Sunday, just days after claims that he injected his girlfriend, Bobbi Kristina Brown, with “a toxic mixture” on the day she was found unresponsive in her Atlanta home.

“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 private Twitter account, lifting a lyric from Jay Z’s “Lost One.”

Last Thursday, he shared another message that appeared to be about Brown. “When you would do anything in the world to spend five min with her again,” he wrote.

As previously reported, a document in the $10 million wrongful death civil lawsuit filed against Gordon by Brown’s conservator alleges that “Ms. Brown died due to a violent altercation with Defendant (Gordon) after which he placed her in a bathtub, unconscious, after he injected her with a toxic mixture.”

Gordon has not been arrested in connection with Brown’s death, and his lawyers previously called the initial “toxic cocktail” allegations “slanderous and meritless.”
