BOCA RATON, FL (WFLX) - DNA from a 1989 sexual battery case was discovered leading to the arrest of one 59-year-old Boynton Beach man.

It happened on March 15, 1989 at about 3:15 in the afternoon.

The victim had just finished washing her car in the parking lot of her apartment complex in the 1000 block of Northwest Avenue.

She returned to her apartment, leaving the door open.

A few minutes later, as she was in the kitchen, she turned around and was confronted by an intruder with a large knife.

The suspect grabbed the victim and led her to the living room, where he closed the door.

The suspect then led the victim to the bedroom, where he used his knife to make her take off her bathing suit.

The suspect then sexually battered the victim. When the suspect was finished, he ran out of the apartment.

At the time of the offense, Boca Raton officers, detectives and crime scene technicians conducted an exhaustive investigation which included processing the crime scene and collecting evidence, canvassing the neighborhood, interviewing the victim and witnesses, and compiling a composite sketch of the suspect.

However, a viable suspect never emerged and the case went cold.

On June 28, 2006, an Evidence Custodian for the Boca Raton Police Services Department, while reviewing evidence from cold cases, submitted the sexual battery exam kit to the Palm Beach County lab for analysis.

On July 29, 2010, detectives received information from PBSO that the FBI had matched the suspect's DNA profile.

On August 30, 2010, detectives received the official report from PBSO which stated that while searching the National Convicted Offender Database, the suspect's DNA profile matched convicted offender John Leonard McKenzie.

After receiving a warrant, Boca Raton detectives arrested McKenzie Wednesday for armed sexual battery and armed burglary with a battery.

McKenzie is reportedly the manager of Beacon Property Management in Boca Raton.
