In a statement, Fort Bend Sheriff Troy Nehls said that the incident happened 'so quickly'.
"It really happened so quickly.
"You hear the glass breakage. You’re startled, you get out of bed. And then, within just a few seconds or so, there’s gunfire."
The sheriff continued: "It’s sad. Sad. We have a homeowner here in Fort Bend County who is no longer with us — and the father of two small children. Breaks your heart."
Local resident Kimberley Patele told TV station KHOU that this level of violence is unusual in their neighbourhood, saying it's the kind of suburb where people feel safe to leave their doors unlocked.
"We’ve left our doors unlocked because we feel this is such a quiet neighbourhood," she said.
"It’s pretty shocking, to be honest".
There have been no reported suspects to date.
