Newly-obtained police reports have shown that Whitney Houston's daughter was involved in a traffic accident that injured two people days before she was hospitalized.
Police in Roswell, Georgia, say Bobbi Kristina Brown was driving a Jeep Liberty on January 27 when she lost control, crossed into oncoming traffic and collided with another vehicle.
A passenger in the Jeep and the other car's driver were taken to the hospital.
Four days later, on January 31, Brown was found unresponsive in her bathtub, and her family said she's been 'fighting for her life' since.
Records also show that Brown's partner, Nick Gordon, called police in July 2013 saying she had fallen and was unresponsive.
The officer wrote at the time that she was disoriented and went to the hospital.
Bobbi Kristina's aunt has said she believes Nick Gordon will '110 per cent' be charged with a crime related to the 21-year-old's injuries.
Leolah Brown, Bobby Brown's sister, said she thinks he had a part in the incident on January 31, when Bobbi Kristina was found face-down in a bathtub at the couple's Roswell, Georgia townhouse.
No one has been charged in the incident or named as a suspect, and Gordon has not responded to the family's accusations.
Bobbi Kristina, the 21-year-old daughter of Whitney Houston, has been on a ventilator in hospital since she was found, but Leolah Brown insisted she is 'doing good' and has even opened her eyes.
Gordon was taken in by Houston as a child and brought up as Bobbi Kristina's brother - but after Houston's death, they started a romantic relationship and last year, they claimed they had married.
In the Fox interview, Leolah said she does not think Gordon has been a good influence on her niece.
She added that she had lived with Whitney Houston and Bobby Brown and had helped them look after Bobbi Kristina, but never saw Gordon around the house.
She also reiterated her brother's statement that the young couple are not married, despite their claims on social media last year, and hinted that they had been through some trouble.
Leolah also dismissed the idea that Bobbi Kristina would have hurt herself.
As for her niece's current condition, she rubbished reports that Bobbi Kristina was brain dead.
'It's been very, very painful for everybody. Mainly Bobby, because that's his baby,' she said of her brother, Bobby Brown.
But she added that they remain hopeful, especially because she has given them 'signs' that she'll recover, such as opening her eyes, she said.
There is also no truth to the idea that Bobbi Kristina would be removed from life support today - the same day her mother died three years ago - she said.
The family has been at Bobbi Kristina's bedside in Emory University Hospital in Atlanta, where she remains in a medically-induced coma after being found submerged in bathwater.
No one has been charged or named as a suspect in the January incident. Gordon has not commented publicly about his girlfriend's condition and has not responded to the family's accusations.
Earlier this week, RadarOnline reported that bruises were found on Bobbi Kristina's body. Gordon told a friend that he caused them while performing CPR.
It has also emerged that one of their neighbors reported a domestic dispute at her address the week before she was found, according to a 911 call made by her security guard on January 23.
The caller told a 911 dispatcher that one of the neighbors had reported a fight at the address. They said they saw people 'hitting each other and swinging' outside the three bedroom townhouse.
He did not give descriptions of how many people were fighting or who they were .
The ongoing investigation and limited details being provided in Miss Brown's case have fueled speculation about her condition and the circumstances that led to her hospitalization.
