Someone was pocketing the pension checks of a deceased city employee, according to court papers.

The city Police Pension Fund is trying to unmask the person who deposited more than $41,000 worth of payments for Charles J. Kelleher Jr., who died in November 2015.

The fund didn’t learn of Kelleher’s death until April 2017, and wants Brooklyn Supreme Court to order Wells Fargo Bank to identify the thief.
