Nick Gordon tweeted out a message about his "pain" on Sunday, just days after new accusations claim 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," Gordon wrote on his private Twitter account. "Somethings can't be explained what caused it. When I lost you I lost it."

This is 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.

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

On Jan. 31, Brown was found unresponsive in a bathtub in her home and was taken to North Fulton Hospital in Roswell, Georgia, where she was put on a ventilator to assist her breathing. She was later placed in a medically induced coma at Atlanta's Emory University Hospital. Nearly two months later, Brown was moved to a rehabilitation center, where she remained until June 24, when she was moved to a hospice center.
