Family and friends are remembering a 13-year-old girl, whose death is being investigated by the Austin Police Department.
An estimated 75 people showed up Wednesday night to remember the 13-year-old girl who family and friends say always had a smile on her face.
Family members set up a small memorial in the front yard of the home on Lake Hurst Drive, with pictures and a poster board that read, "to our angel Sophia, never be forgotten."
Friends and family exchanged moments and good memories they had of her while everyone held a lit candle in memory of Sophia.
FOX 7 spoke with Martinez's mother, Mary Ann Herrera. She says she just wants the truth, and talked to us about the last time she talked to her daughter, which was over text message New Year's Eve.
"Sophia was calling me but I couldn't answer the phone with no minutes, so I ended up borrowing a phone and texting her back. She said mom I'm sorry I left, but she said I'm sorry mom, don't be mad, I love you. I told her, Sophia please don't do anything you're not supposed to be doing. So that was the last I heard from her," said Herrera.
An autopsy was performed. The medical examiner is waiting on toxicology results before determining how Sophia died.
A memorial fund has been set up to help the family with funeral expenses. You can donate at any Bank of America, to account number: 586031387504
Martinez was unconscious when she was dropped off at a home in southeast Austin on the morning of New Year's Day.
Police say the girl did not live at the home on Lakehurst Drive, but one of her friends does.
Neighbors say they heard one of her friends screaming for help Tuesday morning when the girl was found not breathing.
Investigators are still trying to find out exactly where she was on New Year's Eve and who dropped her off.
