OKLAHOMA CITY - It's been six weeks since Twanna Brown found out her daughter was dead and coping hasn't gotten any easier.
"I've cried 'til I can't cry no more," she told NewsChannel 4. "But I haven't really got to mourn her death because it's hard to mourn when you really don't know what's going on. I really need to know what's going on, what happened to these two girls that didn't bother anyone."
Brown's daughter, Totinika Elix, 23, and her friend Emily Morgan, 24, were found shot to death in their car in Pittsburg County at the end of August.
Their car was found in front of a vacant home in Bache.
The Oklahoma State Bureau of Investigation has been investigating but has yet to make any arrests.
"It breaks my heart," said Brown, looking at photos of her eldest daughter. "Ask anybody about Totinika and they will tell you they don't have anything bad to say about her. She was really, truly a good kid."
Elix and Morgan were both mothers who leave behind grieving families.
And now their families are pleading for help from the public as state agents follow up on leads.
"It's still early in the investigation, we know this," said Brown. "But you know with a parent losing a child, time is critical. We really need this. We really need someone to come forward."
Brown says her biggest fear is that the case will go cold and she'll be left without answers.
"We just really need closure where I can sit and mourn my child," she said. "Right now we just can't do that. It's really hard for me right now."
