A Texas man murdered his mother, grandmother and uncle — and then took his own life — inside a home that was set ablaze this week, according to a new report.

Authorities were called to the San Antonio home around 6 p.m. Monday following reports that a man was trashing the house, FOX San Antonio reported.

When cops arrived, they found smoke coming out of the home — and discovered two people in their 60s shot to death in the front yard, San Antonio Police Chief William McManus told the outlet.

They have since been identified by relatives as the shooter’s mother, Josefina H. Gonzalez, and uncle, Jose Guadalupe Hurtado.

Inside the house, authorities found the body of the grandmother, 80-year-old Felicitas Guillen, and another body, likely the suspect, whose name has yet to be released, according to the report.

It wasn’t clear how Guillen was killed, but authorities told local outlet KSAT 12 that there was no way anyone could have survived the blaze.

“To lose one loved one, that’s hard enough,” relative Christina Gonzalez told FOX San Antonio. “To lose four, in such a tragic way, coming from your own family, it’s the worst.”

The home was almost completely destroyed — save for her mother’s Bible and a statue of Jesus that were virtually unscathed, Gonzalez told the station.

“I have faith,” said Gonzalez. “I have seen how much my community has come out to help. I have faith, they’re going to help me pull through.”

“Just trying to hang on,” she added. “We were just overcoming the loss of my older sister four years ago. It’s just us now.”

A neighbor who only identified himself as Chris told KSAT 12 he’s had his share of concerns about the suspected killer.

“The guy carried an AK-47 inside the house,” Chris said. “He was not a social guy.”

A GoFundMe page has been set up to raise $15,000 for the family’s funeral expenses.

Guillen and Hurtado will be laid to rest in Mexico. Gonzalez, as well as the shooter, will be buried in San Antonio, according to the page.
