When 9-year-old Trinity Love Jones was found dead in a duffel bag, the pink shirt she wore gave a glimpse into her hopes for the future.
Instead of being a princess, like many girls’ shirts proclaim, Trinity’s had bigger ambitions.
“Future Princess Hero,” her shirt read, with the word “princess” crossed out.
That’s one of the few details authorities have released about Trinity’s death. Many questions remain. Here’s what we know and don’t know about the young girl’s death:
What we know

A man has been arrested and a murder charge filed
Emiel Lamar Hunt, 39, was charged Tuesday in the death of Trinity. He is reportedly the boyfriend of Trinity’s mother, the Los Angeles County Sheriff’s Department said.
She was partially stuffed in a duffel bag
Police said Trinity’s head and upper body were protruding from the partially zipped roll-away black duffel bag.
She was publicly identified a week after she was abandoned
Lt. Scott Hoglund of the Los Angeles County Sheriff’s Department said authorities think Trinity was left in light brush by an equestrian trail the evening of March 3. The body was publicly identified as Trinity’s on Sunday.
She wasn’t in the state’s missing persons database
There is no record of Trinity in the California Missing Persons System, the state Department of Justice said.
What we don’t know
The exact manner of Trinity’s death
The Los Angeles County medical examiner’s office said Trinity’s death was a homicide. But the sheriff’s department has put a security hold on the girl’s autopsy report.
Whether she was dead or alive
It’s not clear if Trinity was dead or alive at the time she was abandoned by the trail, authorities said.
What authorities believe led to the killing
Hunt was arrested Tuesday but officials have not released a possible motive.
Why a second person was arrested
Investigators detained another person but the sheriff’s department say how – or whether – they are connected to the case.
