The Missouri state senator who was tear-gassed while demonstrating in Ferguson, Missouri, over the police killing of unarmed teen Michael Brown, protested the injection of Brown's alleged robbery prior to his death into the debate over whether Ferguson police officer Darren Wilson's actions were justified.

Maria Chappelle-Nadal (D), who represents parts of Ferguson, said in an interview with The Huffington Post on Friday, "It doesn't matter if Michael Brown committed theft or not. That's not the issue. The issue is what happened when Darren Wilson encountered Michael Brown, and when he died -- when he was killed. Those are the only facts that are necessary."

Chapelle-Nadal, who has been critical of Missouri Gov. Jay Nixon's (D) handling of events in Ferguson, went on, "You need to know what happened in their first encounter, and between that, and when Michael Brown was shot," adding "If someone is an alleged thief, that does not equal a shooting, it doesn't equal death."

The community of Ferguson has been joined by the nation in their grief, anger, and demand for justice, after Michael Brown, an unarmed teen, was shot dead by a Ferguson police officer. Demonstrations have been near non-stop, some hostile. Civil rights groups have been pressing authorities for a complete investigation into the killing. On Saturday, Gov. Nixon announced that the FBI and Department of Justice officials were conducting their investigation into the killing of Brown.
