NAPLES, Fla - Detectives with the Collier County Sheriff's Office drove to Central Florida Monday to investigate the robbery a million dollar home in the affluent Windermere community, near Orlando.

"The purpose of sending our folks up there is to talk with the authorities," CCSO Investigations Chief Jim Williams told WINK News.  "What are the similiarities, if there are any?  What are the differences?"

Last week, a trio of robbers dressed as "ninjas" broke into a Windermere home.  They tied up the couple inside and robbed the house.  Security cameras in the home caught glimpses of the suspects in masks.  The victims were not seriously hurt.

The crime caught the attention of local investigators after a rash of similar crimes in the Collier County area.  The most recent happened in early April at a home inside the gated Quail West community.  In all five instances, masked suspects have tied up victims during the crime.

There are differences case-to-case, authorities say.  But they admit the similarities are hard to ignore.  The same is true in the Windermere case.

"I absolutely will not say they are connected, but it would be wrong not to go," Williams told WINK News.  "We have to follow every possible lead.  Even where there's not a lead, we have to dig until we find something."

The reward for information leading to an arrest and conviction in the case is now up to $26,000, according to Williams.  Detectives have received numerous tips and continue to investigate.
