The Monroe Police Department is welcoming a new K-9 to its force.

Keen is an 18-month-old German shepherd who will graduate from K-9 academy on Friday.

Keen is named after fallen former NYPD Detective Brian Mulkeen, who was killed by friendly fire while attempting to make an arrest in the Bronx in 2019.

Mulkeen lived in Yorktown Heights but grew up in Monroe, where his roots still run deep.

"He's a hometown hero here in Monroe, he's a Monroe Woodbury graduate,” says Chief Darwin Guzman, of the Monroe Police Department. “We felt having the opportunity to name our K-9 in memory and dedication to Brian Mulkeen would be an honor for us to be able to do so."

Keen met NYPD K-9 Mull on Thursday, who is also named after Detective Mulkeen.

Keen’s first day on the job is Friday.
