Merhige has been on the run since Nov. 26. The FBI has now joined the Jupiter Police Department and the U.S. Marshal's Service in the hunt for Merhige. Law enforcement believes Merhige has fled the state , according to documents filed in federal court on Dec 4th.
In the court papers, investigators noted that Merhige withdrew a "large amount of cash" and collected clothing and a computer hard drive prior to the shootings.
The reward for Merhige's capture has increased to $35,000, thanks to a donation of $10,000 from a local business that added to the original $25,000, according to Jupiter Police. The business has asked to remain anonymous.
