Cold blooded thief makes away with something that is essentially useless

 eye_on_crimeA UPS-delivered package was stolen from a porch in the 2500 block of West Humboldt. What did the sneak thief get away with? A blood pressure cuff. I wonder what those are work on the open market. 9:35 a.m. 12/03/2016.
