A murder suspect is now behind bars in North Port. Less than a week after Jaqavies Rivers was found dead inside of a home in the 2400 block of Roxbury Circle, police have arrested 26-year old Marquis Harris. Investigators say Harris lives across the street from the home where the shooting happened. Detectives say Harris got into an argument with Rivers about a burglary, then pistol whipped him before fatally shooting him. Police found a pistol inside his home with DNA evidence on it, and also a spent casing that matches the shell found at the murder scene.
