Authorities say one person was shot and seven more arrested in a St. Louis suburb where a curfew had been imposed overnight, following protests of the fatal police-involved shooting of an unarmed black teenager.

Missouri Highway Patrol Capt. Ronald Johnson said tear gas was fired into the Ferguson, Mo., crowd after officers spotted an armed man in the street. Missouri Gov. Jay Nixon (D) announced the controversial midnight curfew Saturday, saying the “eyes of the world” were on the community.

The Missouri protests are in response to the death of 18-year-old Michael Brown, who was fatally shot earlier this month.

Here’s what to watch on Sunday:

• Nixon is scheduled to appear on both “Face the Nation” and “Meet the Press” Sunday.

The Washington Post details the lives of Brown and Darren Wilson — who was identified as the officer involved in the shooting on Friday — and looks at the three minutes in August that connect the two. • Via the New York Times: “As the news briefing ended, Captain Johnson was asked whether the curfew would continue, but he did not answer.” • The Times also has an interesting portrait of Ferguson, if you’d like to know more about the neighborhood and surrounding community. The Times reports:

Garland Moore, a hospital worker, lived in this St. Louis suburb for much of his 33 years, a period in which a largely white community has become a largely black one. He attended its schools and is raising his family in this place of suburban homes and apartment buildings on the outskirts of a struggling Midwest city. And over time, he has felt his life to be circumscribed by Ferguson’s demographics. Mr. Moore, who is black, talks of how he has felt the wrath of the police here and in surrounding suburbs for years — roughed up during a minor traffic stop and prevented from entering a park when he was wearing St. Louis Cardinals red.

• St. Louis alderman Antonio French, who was arrested at a Brown protest a few days ago, was in Ferguson again Saturday. His Twitter feed has dispatches and images from the night.

He’ll be appearing on “This Week with George Stephanopoulos” this Sunday, according to his Twitter feed.

• The St. Louis Post-Dispatch has profiled St. Louis County prosecutor Robert McCulloch, and their report is also worth a read. It begins:

Robert McCulloch isn’t known to back down.

For decades, the St. Louis County prosecutor has been in the spotlight for everything ranging from his prosecution of Guns N’ Roses frontman Axl Rose to questions about his deep police roots. And for decades county voters have kept him in office.

On Friday, McCulloch faced calls from political foes to step aside in the investigation of the fatal shooting death of unarmed black teenager Michael Brown at the hand of a white police officer. State Sen. Jamilah Nasheed wrote a letter to McCulloch saying prior prosecutorial decisions and his heavy support of Steve Stenger in his defeat of St. Louis County Executive Charlie Dooley in this month’s Democratic primary scarred the black community.
