The fugitive suspected of murdering a man with a hatchet in Nashville, Tennessee this week has been tracked down and arrested in Kentucky. Metro Nashville Police tweeted late Tuesday evening that cops arrested 36-year-old Domenic Micheli. Authorities believe he attacked and killed his former boss, 46-year-old fitness center manager Joel Paavola, early Monday, with a hatchet and another bladed instrument. Police said Paavola was assisting clients with a workout in The Balance Training Center when he was attacked. Paavola had fired Micheli about 14 months ago, according to police. The Secret Service disclosed Tuesday that Micheli was arrested on April 27 in Washington, D.C., after he drove his car to a checkpoint near the White House and refused to move.
