Transcript for Michael Brown's Stepfather Reportedly Being Investigated in Ferguson
tonight, and there's new fallout after the grand jury decided not to hand out an indictment for the police shooting of Michael brown. This evening, a new question. Is Michael brown's step-father now being investigated for what he said afterward? ABC's Steve osunsami back on the story for us. Reporter: They were words in the heat of the moment as crowds gathered on the streets of Ferguson. Louis head, the step-father of Michael brown, clearly upset, as the family was learning that officer Darren Wilson would not be charged for the shooting death of their son. Burn it down! Reporter: And now today, word that police investigating the fires that burned across the city might also be looking at what brown's step-father said that night, whether his words helped start a riot and set the city on fire. From St. Louis county police tonight, "Our department is currently looking into this as part of the entire investigation that includes the arsons, loofting, destruction of property, et cetera." Speaking of Fox News, Ferguson's police chief said they're well aware of the video tape. We are pursuing those comments and there's a lot of discussion going on about that right now. But I can't get into that at this time. Reporter: The family's lawyers have tried to explain. They were upset. The E motions were raw and their son is still dead. Raw emotion. Not appropriate at all. God forbid your child is killed the way they killed. Reporter: Tonight, police are softening their tone, saying they are looking into a lot of things that happened that night but they would still like to talk with the step-father.
