HOUSTON — It's been more than three months since a teenager driving to Galveston with friends to watch the sunrise was shot and killed in Houston.
Louise Wilson, 17, was shot in the heart by a road rage killer on the Pierce Elevated portion of I-45 around 1 a.m. on Sunday, Dec. 10.
A male passenger was also shot but he survived.
Despite a $20,000 reward, a sketch of the gunman, and multiple pleas from Wilson's heartbroken parents, the gunman is still on the loose.
In a renewed push for answers, on Wednesday Crime Stoppers Houston launched 10 digital billboards across the Houston area that feature Louise's picture and the sketch of her killer.
"I'm happy but I'm sad at the same time to see her up there, and I have hope that this is going to help find her killer," Louise’s mother, Krista Wilson, said. "Please, someone speak up, you know who did this."
Wilson went on to describe how painful the last three months have been.
"I just hate not having an ending to this, you know. It's not going to bring my daughter back, but I think it will help with the healing process to know that this person or persons is taken off the street, and they can't do this to anybody else," she said.
Clear Channel Outdoors is donating the digital billboards and they'll remain up for at least three months.
"It's time for us as a community to send a message to those who commit these types of senseless crimes, destroying families one at a time," Andy Kahan with Crime Stoppers said in January. "We're going to find you, we're going to hunt you down and we're going to lock you up."
Homicide detectives said the gunman was in a newer model, black four-door sedan.
- Light-skinned Black male
- Mid-20s
- Short, hairstyle with locs partially dyed blonde.
'You stole her life, you stole her future'
Louise's family said she loved animals and helping people so she wanted to be a K9 officer.
"You stole her life, you stole her future, you stole from our family, you do not value life,” Krista said in January. "When you chose to spray my daughter with bullets, that's when you lost your right to live freely amongst society, Lord willing you will be found.”
Krista said she doesn't know how she's supposed to live without her daughter.
"No words can really describe the magnitude of loss and pain I'm experiencing," Krista Wilson said. "It's been difficult to believe that was my daughter lying in that casket, that it was my daughter put in the ground and that I will never touch her or hear her voice all the rest of the days of my life."
The victim's father, Daniel, had a message for the killer.
"To my daughter's killer, I want to say you are a coward," Daniel Wilson said in January. He said the large reward should haunt the suspect who must now wonder if and when someone will turn him in.
"You'll have to live with that doubt for the rest of your life, having to wonder who might turn you in, your mom, dad, brother, sister or friends," Daniel said. "To those you bragged about what you did to our little girl, how much is your life worth to them is something you'll have to ask yourself for the rest of your life."
Daniel said if the killer is never caught, he'll still "have to face another judgment -- one that is eternal."
"I do pray that you find salvation cause I know you don't have it right now. It's easy to repent and ask for forgiveness," Daniel said. "Maybe one day, we can meet face to face as brothers in Christ."
