CHARLOTTE COUNTY, Fla.- Punta Gorda Police Officers may have found evidence in the case of a woman who has been missing since 1993.

On June 30, 1993, officers responded to the 3700 block of Whippoorwill Blvd. for a report of a missing 64-year-old woman. Frances Hendrickson was last seen by a neighbor driving her 1987 light blue colored Buick station wagon.

Approximately two years ago, the case was reopened using sonar to search City canals for the missing woman's vehicle. Detectives teamed up with the Florida Department of Law Enforcement, Sarasota County Sheriff's Office, and the Lee County Sheriff's Office in the effort. Earlier today, using a new advanced sonar technology, a light blue colored station wagon was discovered in a canal behind the intersection of Whippoorwill Blvd. and Eider Street, just blocks from the missing woman's home. This area was previously searched by air and water numerous times. The Punta Gorda Police Dive Team has secured the location.

An operation to recover the vehicle will begin tomorrow morning.
