CHICAGO -- Police are investigating the deaths of three people who were found inside a residence on the 4600 block of North Kostner Avenue.
The medical examiner says the men are Roberto Cervantes, 38; Joel Cervantes, 29 and Jesus Cervantes, 72.
Neighbors say the men were all related; a father and his two adult sons.
Someone requested a well-being check at the residence Friday afternoon and police discovered the men's bodies inside. All three were reportedly shot.

Neighbors reported hearing several loud "bangs" but they thought it was the men doing home repairs.
