The aftermath of Bobbi Kristina Brown's death is still not over.

Boyfriend Nick Gordon recently made headlines when allegations surfaced that the 19-year-old injected Bobbi Kristina Brown with "a toxic mixture" the same day she was found unresponsive in her Atlanta residence.

Taking things to Twitter, Nick Gordon tweeted a couple of lines from Jay Z's "Lost One," which goes: "Can't run from the pain go towards it. Some things can't be explained what caused it. When I lost you I lost it."

On Thursday, Nick Gordon also shared a message which seemed to be about his late girlfriend: "When you would do anything in the world to spend five min with her again."

According to documents obtained by Entertainment Tonight regarding the $10 million wrongful death lawsuit against Nick Gordon, Bobbi Kristina Brown's conservators alleges:

"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."

Nick Gordon has not been arrested with regard to Bobbi Kristina Brown's death, in addition to his lawyers calling the "toxic cocktail" allegations "slanderous and meritless."

It was on January 31 when Bobbi Kristina Brown was found unresponsive in a bathtub in her residence. She was taken to North Fulton Hospital in Roswell, Georgia where a ventilator was installed to help with her breathing.

Bobbi Kristina Brown was then placed in a medically induced coma at the Emory University Hospital in Atlanta, Georgia. Two months later, Brown was relocated to a rehabilitation center and stayed there until June 24, before being moved to a hospice center.

The daughter of Whitney Houston and Bobby Brown passed away on July 26, 2015 at Peachtree Christian Hospice in Duluth, Georgia. She was 22 years old.
