If at first you don't succeed...
from WINK News on a story from Punta Gorda, FL on 16 Jan 2013
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.
