A second suspect in the brazen mid-Christmas mass theft has turned himself in to authorities:

A man suspected of helping a real-life Grinch swipe $20,000 in parishioner donations from a Queens church during a Christmas-morning Mass turned himself in to police yesterday and returned $6,000 in cash.

Dennis Almodovar, 24, walked in to the 109th Precinct station house with his lawyer yesterday morning and was questioned for several hours before being charged with burglary.

The lawyer also turned over the money, said prosecutors, adding that the rest of the missing donations were nonnegotiable checks that can be replaced.
