The in-laws of Texas mass shooter Devin Kelley attended the church where he shot 26 dead and injured another 20 on Sunday — but they weren’t in the pews during the massacre.

Wilson County Sheriff Joe Tackitt Jr. revealed the connection Monday morning, though it’s not clear what their exact relationship was, according to CNN.

It may have been a motivating factor, according to Texas Gov. Greg Abbott.

“I don’t think this was just a random act of violence,” he told ABC’s “Good Morning America.”

The family members came to the church Sunday after hearing about the shooting, CNN reported.
