(Thursday April 27)  --  Less than a week after the puppy named Mercy died from being set on fire, police now have the man they've been looking for.  Dashawn Brown was arrested after leaving his mother's house in Corinth early this morning after police staked out several locations where he had been seen.  He's accused of setting Mercy on fire, leaving her with burns over more than half her body.  She died Sunday despite more than a week of intensive treatments.  On Saturday, her care-givers from Operation Kindness will hold a public memorial in Carrollton.
