CHARDON -- On Wednesday, a Geauga County grand jury indicted two men in connection with the 2010 death of Daniel R. Swan.

Thursday afternoon, the Geauga County Sheriff and Geauga County Prosecutor Jim Flaiz held a press conferenceregarding the indictment.

Sheriff Dan McClelland says a lead developed out of an unrelated burglary investigation in July 2012 suggested a suspect in the case and started a long investigation that led to the two men indicted.

Theindictment relates to the assault and eventual death of Daniel R. Swan. The alleged incident took place exactly three years ago today, on July 25, 2010.

Swan later died in August 2010.

The indictment chargesMatthew R. Boone, of Rome Township, with seven counts, includingaggravated murder, complicity to murder, felonious assault, complicity to felonious assault and tampering with evidence.

The indictment also charges Dustin Plottke, also of Rome Township, Ohio, with aggravated murder, murder, felonious assault and felonious assault with a deadly weapon.

Boone is now 23 and Plottke is now 26. Rome Township is located in Ashtabula County. Both are in custody. Both have extensive criminal records in Ashtabula County courts, including breaking and entering, arson and theft.

Swan, was a2010 Ledgemont High School graduate.

On the night of July 24, 2010 Swan went to a party and later left with a friend. At one point during the night, the teens separated.

The friend found Daniel four hours later lying in the middle of Sidley Road with a critical head injury

Officials now say that Boone and Plottke were driving down Sidley Road with Boone as the driver when they saw Swan walking on the side of the road.

As they passed Swan, Plottke opened the passenger door, striking and knocking Swan into the ditch. Boone then turned the vehicle around and drove back towards Swan, who was climbing out of the ditch.

The vehicle stopped. According to the sheriff, bothexited the truck and confronted the teenandPlottke struck Swan in the head with a "pipe-like" object.

Swan's condition worsened and he died on Aug. 17, 2010.

Sheriff McClelland says the pick-up truck used in the incident was chopped up and scrapped.

Swan did not know Plottke and Boone.

The sheriff says there was no known motive other than this was, "a crime of opportunity. A random act of violence," McClelland said.
