A little boy in Texas has been left orphaned after his family was wiped out in a horror crash allegedly caused by a drunk driver as they returned home from a holiday party.

Three-year-old Dieguito was the only member of the Contreras family to survive the collision, which happened around 2am on December 20.

His mother, Lizbeth Rodriguez Contreras, 27, and his five-year-old sister, Camila Peña, were pronounced dead at the scene. 

The boy and his father, Diego Peña Jr, 26, were airlifted to hospital following the crash.

Despite doctors’ efforts, the father later died from his injuries. The young boy remains in hospital in stable but critical condition.

Authorities arrested Majesti Faith Lee, 27, charging her with intoxication manslaughter and one count of intoxication assault.

Investigators said the family of four, from Harris County, was driving north from the holiday party when Lee was allegedly traveling southbound in the northbound lanes.

Officials confirmed alcohol was a contributing factor in the crash.

Lee was also airlifted and treated for non-life-threatening injuries, according to the press release.

‘Our hearts are with the family as they endure an unimaginable loss,’ said Fort Bend County Sheriff Eric Fagan.

‘This tragedy is a painful reminder of how quickly lives can be changed when impaired driving occurs, and why making responsible choices behind the wheel is so critical.’

The siblings of Lizbeth and Diego set up a GoFundMe in an effort to help support the young boy and the grieving family cover medical expenses.

‘Lizbeth and Diego’s world revolved around their children, as was evident since their young family was inseparable,’ the GoFundMe wrote.

‘Diego recalls the moment his life changed when he found out he was going to be a father. He took naturally to being a very involved dad and took great pride in working overtime along with Lizbeth to provide for their young family.’

The fundraiser said Lizbeth absolutely loved being a mother to her mini-me, Camila, and to her three-year-old son, and that she was also a beloved 4th-grade teacher at Metcalf Elementary School.

Her daughter was also a pre-k student at the same school, and they got to spend every day together, which Camila absolutely loved.

‘Camila had a contagious smile that would make it impossible for you to have a bad day when you were with her,’ the GoFundMe added.

The fundraiser noted that Camila’s best friend was her little brother.

As the family grieves, they ask for thoughts and prayers. The GoFundMe nearly reached its $100,000 goal.

Lee’s bond has been set at $1,050,000.
