DNA Match Prompts Extradition and Charges in 1987 Deerfield Beach Assault

Modern testing of preserved evidence enabled prosecutors to charge a man already imprisoned in California.

Overview

  • Gregory Rollison, 60, was extradited from a California state prison to Broward County on Monday, Aug. 3, 2026, after Broward investigators said DNA from preserved evidence matched him and charged him with two counts of sexual battery and one count of armed burglary.
  • The original attack occurred July 16, 1987, when an 85-year-old woman was tied up, beaten, robbed and sexually assaulted twice at knifepoint after a suspect entered her Deerfield Beach apartment through a sliding balcony door.
  • Detective Andrew Gianino, who responded to the 1987 scene, reopened the cold case and sent evidence to the BSO Crime Lab, where modern DNA testing produced a profile that matched Rollison.
  • A judge found probable cause and set bond amounts for the Broward charges, but California authorities have placed a custody hold that will prevent Rollison’s release even if bond is posted.
  • Because the victim died years ago, prosecutors will rely on the DNA-linked evidence and the original case file to move the case forward, a result that highlights how new forensic methods can revive long-unsolved crimes and prompt similar cold-case reviews.
