A young Texan family were on the way to their son’s fifth birthday part, but they never showed up.

Maya Rivera, 24, Ray Shawn Hudson, 28, and their son Ray Shawn Hudson Jr were reported missing after failing to arrive at a park near their home on June 10.

When Robert Satterfield was spotted driving Rivera’s car, he became the primary suspect.

Now the 36-year-old man has been charged with their murder after leading police to a rural property where charred human remains were uncovered.

Satterfield was arrested and held on a US$305,000 bond, local media reports.

Investigators believe the bodies belong to the missing family.

However, the remains are “at this point unidentifiable” because there was an “attempt to dispose of the bodies by burning them,” the Wharton Count Sheriff’s Office said.
