A Houston family is mourning the loss of five relatives, including three children, who were killed Sunday afternoon in a single-vehicle crash in Seguin.

Guadalupe County Precinct 1 Justice of the Peace Judge Darrell Hunter says preliminary findings indicate the family’s SUV may have hydroplaned on wet roads and potentially overcorrected before plunging off an overpass.

The crash happened shortly before 1 p.m. Sunday as the black Chevrolet Tahoe traveled eastbound on I-10, according to Seguin police.

Investigators say the SUV left the roadway, went off the overpass and landed on FM 725.

All five people inside were killed.

The victims were identified as 30-year-old Omar Lumbreras Oliva and 31-year-old Ana Deli Lumbreras of Porter, Texas. Their three children, ages 13, 6 and 3, have not yet been identified by authorities.

Family was returning home from San Antonio trip

The family was heading back to Houston after spending the weekend in San Antonio when the crash happened, according to Omar’s sister, Gloria Lumbreras.

Gloria says police went to her mother’s home to deliver the devastating news.

“I arrived to my mom’s house and there was an ambulance there because my mom got sick and I also fainted. I’m seven months pregnant,” Gloria said.

She remembers her brother as a devoted family man who always made sure his loved ones were taken care of.

Gloria described Ana as a good mother and said her 13-year-old nephew loved soccer. She also remembered her two nieces as intelligent children who loved school.

“He always invited everyone in the world to his house. He was always happy and when he could he would say, ‘Come to the house, we have everything you need here, come eat.’ His house was always filled with family,” Gloria said.

Family starts fundraiser to help with funeral expenses

The family is now facing the difficult task of arranging five funerals while trying to bring their loved ones home.

A GoFundMe fundraiser has been started to help cover funeral and related expenses. It had raised more than $40,000 at the time of this report.

Gloria says the family is grateful for any help as they navigate the unimaginable loss.

“I want to get my brother’s body and I want to bring his family home. I know it’s not easy when it’s one or two people, but we have five, and if anyone can find it in their hearts to help us, we would be very grateful,” she said.
