Alabama police officer, Sean Tuder, was fatally shot on Sunday in the process of following up on an investigation in Mobile, according to police.

Police Chief Lawrence Battiste told reporters that Officer Sean Tuder “was doing some follow-up work on an investigation and was gunned down by a suspect.”

The suspect, Marco Perez, is currently in police custody, though Battiste confirmed he wasn’t specifically sure if he was the shooter or not.

According to Fox 10, Perez was wanted by Mobile police for property theft and for supposedly filing a false police report. It’s said federal authorities were also seeking him for probation revocation.

Having been named “Officer of the Month” in August 2017, Tuder had been with his department for less than five years. As per Battiste’s report, he “was really just getting into that part of his career where he started having a really major impact on not just the people in the community, but the men and women who work here in this department.”
