The male offenders work as a team to get inside the homes to steal jewelry, cash and other valuables.
One person goes to the door trying to distract the homeowner while the others go in and take whatever valuables they can find.
Last week, the four men robbed a man on Peterson near Kostner. The man in the house was lured outside by someone claiming to be a tree trimmer for the city. However, the other three went into the house to steal jewelry and cash before jumping into their car and speeding away.
Most of the robberies occurred in the afternoon or early evening hours.
In another incident last month, the offenders posed as water department workers and had the elderly homeowner go to the basement to turn off the water while they robbed her upstairs.
The robberies have hit several different neighborhoods:
The suspects were described as two to four males between the ages of 25 and 60 standing between 5-foot-6 and 6-foot-2.
