The Midland police officer identified as Nathan Heidelberg, 28, died around 8:30 a.m. at a local hospital, Midland's KOSA-TV reported.
The homeowner, identified as David Charles Wilson, was arrested Tuesday and charged with manslaughter before being released on bond, the Midland Reporter-Telegram reported.
Wilson's attorney Brian Carney told the paper that his client believed that his family was experiencing a home invasion and "only fired his weapon to protect his family."
“We would like to express our deepest sympathies to Officer Heidelberg’s family and the Midland Police Department for the events that led to his death,” Carney said.
Heidelberg is a five-year veteran of the Midland Police Department.
"I'm asking our community to come together today and this week to lift our fallen police officer, Officer Heidelberg, his family and the Midland Police Department family in prayer," Midland Mayor Jerry Morales said on Facebook. "This is a tragic loss for our community."
