It’s been one year since Bobbi Kristina Brown died, succumbing to her injuries six long months after she was hospitalized in connection with a nearly-fatal drowning incident. The only child of Whitney Houston and Bobby Brown was taken to Emory University Hospital only to be transferred several times to other facilities. Both the Brown and Houston families have vowed to get justice for her and, one year later, their mission continues.

Police in Roswell, Georgia, began investigating Bobbi Kristina’s cause of death immediately after it happened. While E! News reports that their case has closed, the Fulton County District Attorney’s office continues to dig for any clues into what may have occurred on Jan. 31, 2015 — the morning she was discovered unconscious in the bathtub of her home. The D.A. has released little information about their investigation, but Bobbi Kristina’s family has made it no secret that they believe Nick Gordon — her live-in boyfriend who was allegedly physically and emotionally abusive to her — is to blame. As E! points out, Gordon has not been charged or arrested, but is slated to stand trial. Bobbi Kristina’s estate is suing him for her wrongful death, which his legal team claims is unnecessary. They state that he lost “the love of his life” when Bobbi Kristina, who was just 22, died on July 26, 2015 and is still in mourning. Despite this fact, her family and the authorities assigned to the case are not giving up.

“There is no statute of limitations but, at some point in time, if [someone] were to be indicted, juries are more difficult to convince,” said Darryl Cohen, a criminal defense attorney. “The longer from the time of the incident to the time it goes to trial, it’s harder. In my view, most would be like why did they wait so long? Unless there is some evidence, scientific, or an eyewitness that came out of the woodwork — that clearly is significant. If it’s nothing new then it makes jurors much more reticent to convict.”

Despite claims he is “grieving,” Gordon has also found time to assemble an all-star team of lawyers. On June 10, Bobbi Kristina’s father did an interview with Robin Roberts on ABC’s “20/20.” During the interview he was asked about his daughter’s death as the one-year anniversary approached. He claimed that he had no doubt that Gordon was responsible for Bobbi Kristina’s death — and the “Every Little Step” singer didn’t stop there. Bobby, 47, told Roberts that it was no coincidence that both his daughter and ex-wife died in similar bathtub drowning incidents. Though he refused to use Gordon’s name during the interview, he made it clear that he felt he had killed Houston and done the same to Bobbi Kristina three years later.

“It’s not a mystery to me. The same thing that happened to my daughter is what happened to Whitney,” he said (via People). “There’s only one person that was around on both occasions.”

Bobbi Kristina’s father has been one of the most outspoken accusers of Gordon. In September 2015, almost two months after her death, he released a statement to Us Weekly through his lawyer, Christopher Brown, in which he made some lofty claims about Gordon. He told the publication that he felt Gordon “harmed Bobbi Kristina Brown.” The statement also discussed their plans to move forward with legal proceedings involving Gordon, revealing that he would be forced to testify under oath as a result of the accusations against him.

“In regards to the civil litigations, we believe we know who harmed Bobbi Kristina Brown, and his name is Nick Gordon,” Bobby’s lawyer told Us. “Mr. Gordon made headlines when he filed his Motion to Dismiss the lawsuit pending in Superior Court that seeks to hold him responsible for $40 million in damages. However the motion was frivolous and instead of having it heard by the Court, he has chosen to withdraw the motion, ending that matter so that he could avoid having to give his deposition, which was scheduled for the day he withdrew the motion. Mr. Gordon will now have to give his deposition under oath.”

Much of the speculation surrounding Gordon’s involvement in Bobbi Kristina’s death stems from reports that he was manipulating her during their relationship. A lawsuit, filed by Bedelia C. Hargrove, claimed that while they were together, Gordon stole money from Bobbi Kristina, perpetuated the farce that they were married to limit her interaction with other men, among other charges. He is also accused of providing her with a “toxic cocktail” on Jan. 31, 2015, before she drowned in a partially filled bathtub, leaving her with limited brain function. The estate was seeking $10 million in damages.

It remains unclear when Bobbi Kristina’s estate will face off against Gordon and his team of lawyers in court. At present, no further evidence against him has been made public.
