Attorneys for the Indianapolis man awaiting sentencing on charges stemming from a deadly house explosion allege he's being mistreated in jail. An emergency petition filed on Mark Leonard's behalf claims the St. Joseph County Jail has violated his constitutional rights… holding him in a padded “suicide prevention” cell where he must sleep on a “cold steel table.” Saying he can wear only a thick smock and was not allowed to shower for 16 days.It requests that he be returned immediately to a segregation cell where he held before he was convicted July 14 on murder, arson and conspiracy charges stemming from the 2012 explosion that killed two neighbors.
