Malery Martinez would have turned 17 on Dec. 11, but on Wednesday night -- the night that would have been her birthday -- instead of celebrating, her family mourned her loss.
On Sept. 7, Martinez, an O'Connor High School student, was killed in a car accident off Highway 16 near Reyes Canyons in Helotes.
She was a passenger in the car her mother was driving when a pickup truck driver ran them off the road, causing their car to hit a tree.
Her family is now trying to make changes to that stretch of highway so similar accidents never happen again.
Martinez's family has now made it their mission to get drivers to slow down.
They've met with Texas Department of Transportation officials in an attempt change the speed limit from 65 mph to 55 mph.
“They're looking at, hopefully, slowing down traffic out here, which we know is a major reason for the accident happening," said Homero Elizondo, Malery’s father.
The family not only wants the speed limit reduced on Highway 16, but also to have stop signs put in.
"They're also going to run studies on the crossovers ... and possibly putting a stop sign there so they can stop traffic," said Elizondo.
Her family say they can only hope these changes will save lives.
"Nothing is going to bring Malery back -- we realize that -- but we can definitely try to do something to prevent somebody else from going through what we've been going through over the last three months," said Elizondo.
Police are still looking for the driver of the silver F-150 pickup truck that investigators believe caused the fatal accident.
