Police made the grim discovery after responding to a welfare check at 5:30 p.m. when a family babysitter and a relative reported they had not heard from or seen the family since the previous night.

“Evidence on scene indicated the incident was a murder-suicide in which the male shot the three victims and then shot himself,” police said in a statement.

Matthew and Thy Mitchell were known around the Houston community as the owners of Travelers Table, a restaurant serving “globally curated cuisine” inspired by their family’s travels across the world, Chron reported.

They later opened another restaurant called Traveler’s Cart, serving global street food, according to the local outlet.

Matthew received a bachelor’s degree from Emory University and worked as a writer and journalist in London, Paris, and New York City, according to his website’s bio.

After returning to Texas, he attended Rice University and worked as a CEO in the pharmaceutical industry. He transitioned into the restaurant industry over a decade later, according to his website’s bio.
