A Shreveport man's been arrested for victimizing elderly citizens.  37-year-old Donnie Russell is accused of making unsolicited visits to his victims' homes and offering to make various home repairs for them.  He then asked them for money to do the work and never returned.  He's been booked into Caddo Correctional Center on a charge of missapplication of payment by a contractor.  Police think he may have defrauded others who just haven't come forward and reported it.  They're asking anybody who thinks they may have been a victim, too, to contact Detective Roger Courtney at 673-7004  or Caddo-Shreveport Crime Stoppers at 673-7373.
