The 15-year-old loved his dog, and every night he would take his dog out for a short walk before going to bed.
During that walk on Friday night, a car hit the teen and took off.
"Whoever you are, whoever did it, they need to come forward," said Tammy Walker.
Tammy Walker pleads for the driver who hit and killed her 15-year-old son Trenton to come forward.
"Because of that accident I can no longer speak to my child, or kiss my child, this was somebody's child, he was just not trash to leave on the street for dead," said Tammy.
Trenton Matthews was walking his best friend Jorey when a dark-colored sedan crashed into him and drove off. It happened Friday night around 10 p.m. near 16th Street and Montebello.
Jorey was able to run home, his paw was cut up, but he survived. Trenton died at the hospital hours later.
"Trenton was very charismatic, no matter who he met he would turn a sour mood into a smile into an instant," said Tammy.
"Just walking the dog and you know my son is gone," said Deonton Walker.
Trenton was a freshman at North High School. His family is struggling to pay for funeral expenses. Right now, they can't afford to take Jorey to the vet to make sure his paw is okay.
"The person that killed my sweet nephew, please come forward... I didn't say goodbye, I didn't get to say goodbye to him, just show your face, we need closure, we don't get to see Trenton anymore," said Lakeshia Benn.
The family is holding a vigil at the site of the crash Monday evening. They have opened an account to help pay for funeral expenses. You can donate at any Bank of America branch, reference Trenton Matthews.
Police continue the search for a dark colored sedan, possibly a Lexus.
