Not much is known yet about what exactly happened to Bobbi Kristina Brown, who remains in a medically induced coma after being found unresponsive in her suburban Atlanta home.
Police have said they are treating her case as a criminal investigation.
The 21-year-old daughter of musical giant Whitney Houston was found in a bathtub full of water on January 31.
Here’s a look at the lead-up to when Brown was rushed to the hospital:
1. Car crash
On January 27, Brown was driving and lost control of her silver Jeep Liberty, crashing into a gray Ford Taurus.
The driver of the Ford and a passenger in her Jeep were injured and transported to a hospital, according to a report from Roswell, Georgia, police.
Brown was not hurt.
2. Call to police
Police had been to Brown’s residence recently.
Somebody reported a fight there on January 23, but nobody answered the door and officers found no evidence of an altercation, said Roswell police spokeswoman Lisa Holland.
3. Online posts
Brown’s last tweet before being hospitalized showed excitement for her future.
Her other posts provide a window into the young woman’s mind.
She often wrote about the loss of her mother, who was found in a bathtub at a hotel near Los Angeles on February 11, 2012, hours before she was to attend a pre-Grammy Awards party.
A coroner ruled Houston’s death an accidental drowning, with heart disease and cocaine use listed as contributing factors.
Brown is her only child.
