HOUSTON -

A family is mourning the tragic death of a Houston mother who died after her vehicle stalled along the Beltway.

Family members say 37-year-old Trinice Davis had pulled over because of a flat tire Monday morning. Her hazard lights were on when the driver of another vehicle slammed into her car.

Davis' brother, Donald, said he was on his way to help his sister when he witnessed the crash. He says he ran to help his sister and called 911

Police say Davis' vehicle was stopped in the right lane of the service road when she was hit by another driver.

"They came to the car and told me she didn't make it,"said Donald. "There was nothing I could do. I was almost there -- moments away."

According to the family, Davis was on her way to work the morning of the accident after working a double shift the day before.

Family and friends say Davis provided not only for her own three children, for her nieces and nephews. Thirteen people lived in her home.

Now, they are now trying to figure out how to move on without their loving mother, sister, and aunt.

"She did everything," said friend Aviance Wilson. "She took care of the whole family. So they're going to need a whole lot of help. Especially for the kids."

The family says before Davis died, she had done all of the Christmas shopping for the kids.

Now before they mark the holiday, they will lay her to rest on Saturday.

The Houston Police Department says the driver of the truck was speeding and was questioned at the scene. Officials say the investigation is ongoing, but at this point no charges have been filed.
