The mother of a slain teen blasted a Bronx judge on Thursday for releasing her son’s killer without bail following a recent gun bust.

“If you can’t handle the caseload, you need to do another job,” fumed Juanita Young, 66. “If you can’t make the correct call, step aside.”

In a particularly poignant plea, Young also said Judge Jeanine Johnson should “take two seconds to think about the next person.”

Young’s 16-year-old son, Mario Young, was gunned down in Far Rockaway in 2006 by Shakeil Chandler, then 19.

Chandler served an eight-year prison term for manslaughter and was paroled in 2014.

The Post exclusively revealed that the reputed Crips gang member was arrested following an Oct. 4 shooting and cut loose despite a prosecution request for $75,000 bail.
