Jailer’s trial in ex’s slay

A correction officer shot his ex-girlfriend to death almost 13 years ago to dodge “child-support obligations,” prosecutors said in opening statements at his murder trial in Queens yesterday.

Christopher Clavell, 48, of Staten Island, is accused of killing Barbara Perez in August 2000 behind the Ridgewood gym where she worked.

“The defendant complained about his financial woes and was enraged with Perez for his child-support obligations,” assistant DA Richard Schaeffer said during his opening.

Perez, 30, was hit with one bullet to the chest — and eight to the head.

If convicted, Clavell faces 25 years to life.
