Jan. 23, 2013 -- Westchester County District Attorney Janet DiFiore announced today that Alberto Plasencia (DOB 07/19/86) of 611 Bronx River Road, Yonkers New York has been arraigned on a Felony Complaint charging him with:

  • one count of Murder in the Second Degree, a class "A-1" Felony,

relating to the 2004 death of Marie McSweeney.

On April 24, 2004, between 4:15 and 4:30 p.m., on the southbound Sprain Brook Parkway in the area below the Kimball Avenue Bridge, the victim, with her 87 year mother in the front passenger seat, was struck by a large piece of asphalt 10" x 7" x 3" that crashed through the driver's side windshield of her car. The asphalt struck the victim on the left side of her head.

The car traveled about one third of a mile veering onto the right shoulder for 800 feet, striking a shoulder guardrail support beam, veering back onto the shoulder, traveling across area of Bronx River Parkway split and ultimately into wooded area near the Desmond Ave off ramp.

Both the victim and her mother were transported to Jacobi Hospital. Marie McSweeney pronounced dead at the hospital.

Numerous witnesses traveling on the parkway saw various aspects of the crime.

Yonkers police responded and investigated the incident at the time.

In 2009, based on new information developed, Yonkers homicide and Cold Case detectives reopened the case, putting significant resources into the investigation.

The defendant was arrested yesterday by Yonkers Cold Case detectives.

The defendant was remanded.

His next court date is Jan. 31, 2013.

The defendant faces a maximum sentence of 25 years to life in state prison.
