'Oh my God dude - this is crazy man,' Heartbreaking new footage shows moment Texas man found out he'd become a widower after wife was shot on her driveway while preparing for garage sale in 2019 murder that's stumped cops

Footage has emerged showing the emotional moment a Texas man found out he'd become a widower after his wife was gunned down on their driveway. 

Elizabeth 'Liz' Barraza, 29, was outside her Tomball home on January 25 2019 when a black pickup truck pulled up and parked across the street. 

Surveillance footage captured the suspect, getting out of the truck and quickly walking toward Barraza's home and shooting her at point-blank rage. 

In newly surfaced video footage that was posted to YouTube, the moment her husband Sergio Barraza finds out about her demise has been revealed. 

The footage, from the in-car camera of a Harris County patrol car, shows Barraza wailing in agony and telling officers: 'Oh my God dude. This is crazy.'

Barraza then questions officers, saying: 'So they just shot her and left?' in the video that was verified by ABC13. 

He also tells officers: 'I leave, and I just saw on the camera, this vehicle pulls up and turns around. 

'I guess right there, and then I don't hear anything for a second. I heard four shots and a scream and then that's it.'

Speaking to the outlet, Barraza said: 'It tears me apart to see that. It's hard to watch myself go through that and remember all of that.

'It's really tough re-living all of that. I hate that we haven't had this solved yet.'

The previously released surveillance footage shows a person, who is thought to be in disguise approach Elizabeth Barraza, shooting her and fleeing.

According to ABC13, the shooter had said 'good morning' to Barraza before using a revolver to kill her so as not to leave any trace behind. 

The video shows Barraza appearing to freeze at the sight of the shooter and taking a step back when they approach her.

Just eight seconds pass before the suspect lifts their arm and shoots her at point-blank rage, firing three times.

Barraza falls to the ground and the suspect steps over her body and fires one more shot.

They are then seen sprinting back to the car and speeding away from the scene.

Neighbors called 911 after they heard the gunshots and Barraza was rushed to a nearby hospital, where she died from her injuries the next day.

Sergio Barraza had just left for work mere minutes before his wife was murdered. 

'A coward drove up, approached my daughter, and forever changed our lives,' Barraza's father Bob Nuelle said during a press conference in 2019. 

'An unknown assailant shot and killed an unarmed and defenseless woman in a brutal act that demands justice. We never imagined a life without her. We still can't.'

Barraza's husband Sergio Barraza had just left for work mere minutes before she was murdered. 

Surveillance footage shows him leaving the house at 6.48am. The shooter's truck pulled up to the home at 6.52am, according to ABC 13. 

Barraza's family said she planned the garage sale to make extra money for a trip she and Sergio were taking for their fifth wedding anniversary. 

Barraza was an avid Star Wars and Harry Potter fan. Her family asked mourners to bring wands and lightsabers to her vigil in February 2019. 

Sergio is now remarried and told ABC13 that he still loves Liz and is hopeful an arrest will come soon.

Sergio told the outlet: 'I hope police just have something they're holding onto and getting ready to snap their jaws around it.'
