A nine-year hunt for the fiend who hurled a rock from a Yonkers overpass, killing a Queens woman driving her elderly mom to church, has ended in a murder indictment, authorities said yesterday.

Alberto Plasencia, 26, was charged with second-degree felony murder and faces up to 25 years if convicted in the 2004 death of Marie McSweeney, Westchester DA Janet DiFiore said.

Plasencia was arrested by cold-case detectives, who got new information in 2009, including witness statements from people who knew him at the time of the crime.

McSweeney, 48, was driving south on the Sprain Brook Parkway on April 24, 2004, taking her 86-year-old widowed mother, Mary Pulicicchio, to St. Theresa’s Church in Pelham Bay when a football-sized chunk of asphalt smashed through her windshield.
