Milwaukee police have arrested two 16-year-old suspects for a Wednesday morning crime spree in normally tranquil Shorewood.  Investigators say car windows were broken at several locations so thieves could get inside and steal items.  The first 9-1-1 calls came into Shorewood police at about 7:00 A-M.  While police were following up on those incidents, an emergency call about a strong-armed robbery was received.  The robbers took a woman’s purse and drove off in her S-U-V.  Milwaukee police started chasing the vehicle and caught the two suspects when they got out and started running.  Home surveillance video recorded some of the break-ins.
