Matteson police said they responded to a home invasion on Woodgate Drive on May 18. When officers arrived, they found a woman and her two children, one of them a minor, who had all been shot.
More than a week later, Matteson police said the mother remains hospitalized.
Police have named the mother's ex-boyfriend, Lander Coleman, 43, of Chicago, as the suspect. Matteson law enforcement have asked for help from outside agencies in tracking him down.
