Peggy Goodman, 65, of Chicago was shot to death during a home invasion on March 23, 2018, in the Bronzeville neighborhood. The attack happened around 11 a.m. at the East 37th Street residence she shared with her granddaughter. Benjamin Williams, 31, is accused of breaking into the home with another man, shooting Goodman in the head and then, after returning upstairs, stabbing the granddaughter about 20 times when a gun failed to fire. Goodman died at the scene; the granddaughter survived in critical condition.

Police say Williams was arrested shortly after the incident wearing blood-stained clothing and was held without bail. He faces charges including first-degree murder, attempted murder, home invasion, aggravated domestic battery, and marijuana possession; prosecutors say he was on federal probation for a firearms case at the time. The second man who allegedly took part in the invasion has not been charged or taken into custody.

Does anyone have information about the second person who entered the home or about the events that morning?
