Bold daytime burglars are a bigger and bigger worry in Haltom City.  Police are comparing notes from more than a dozen recent daylight break-ins at homes left empty while the residents were at work.  Plano Police Corporal Eric Peters says -- in most cases -- the thieves entered through unlocked doors or windows.  For the most part, the criminals are grabbing anything they can easily walk away with -- including laptops and small flat-screen televisions.
