CAPE CORAL, Fla. - WINK News is learning more in the timeline of events leading up to the murder of a Cape Coral man.  On Tuesday, Garrett Kern was sentenced to 38 years for the death of his step grandfather, James Arthur.

The Cape Coral Police Department told WINK News, the events they thought happened were confirmed by Garrett Kern in open court.  Kern took a plea deal, confessing to the murder of his step grandfather in 2011.

Kern told investigators he and Arthur left the probation office in Fort Myers in October 2011.  They went to the Arby's in North Fort Myers where they got into an argument and then Kern strangled his step grandfather.

Kern drove to a wooded area off Burnt Store Road in Cape Coral, dumped the body and went to Hustlers Bar to meet friends before fleeing the state.

WINK News spoke with Sally Arthur, James' widow, and she said she's planning to sue the Cape Coral Police Department for negligence.  She said she ended up waiting several days before her husband's body was found and she believes that could have been avoided since two 911 calls were made around the time Kern was at Hustlers Bar.

The Cape Coral Police Department has no comment on the pending lawsuit.
