The shooting death of Sonya Massey is the most recent incident in Sean Grayson's law enforcement career to come under scrutiny. It wasn't the first.

Before being officially hired as a Sangamon County Sheriff’s deputy in March 2023, Sean Grayson needed to pass a drug screening and psychological evaluation.

In the days before the March 21 fatal shooting of Dexter Reed by Chicago police, the same tactical officers involved in the Reed shooting were busy conducting at least 50 traffic stops in west Chicago – with very little result.

Newly released video shows former Sangamon County Deputy Sean Grayson predicting he'll be released from jail and telling deputies he's in jail custody for his own safety.

After initially rejecting calls to step down, Sangamon County Sheriff Jack Campbell announced Friday he would retire by the end of the month – citing the “current political climate” and fallout from the fatal shooting of Sonya Massey.

With tens of thousands of people including delegates, politicians and protestors expected in Chicago this week for the Democratic National Convention, both federal and local law enforcement authorities have promised a secure event.

At least five people were detained by Chicago Police after sections of security fencing were removed along the northern security perimeter near the United Center Monday evening, just hours before the Democratic National Convention was set to kick off in earnest Monday evening. NBC 5 Investigates' Bennett Haeberle reports.

Additional security fencing, locks and cameras were added to the perimeter fencing outside the Democratic National Convention after a group of demonstrators removed a section of fence late Monday afternoon and breached a section of the northern security perimeter just two blocks north of the United Center. NBC 5 Investigates' Bennett Haeberle reports.

As far back as January, a D.C. lobbyist for Chicago Mayor Brandon Johnson estimated the city would need as much $76 million to help pay for Chicago Police overtime, salaries and equipment to provide security for the Democrat National Convention, according to emails obtained by NBC 5 Investigates.

The mother of the suspected shooter charged with killing four passengers Monday aboard a CTA Blue Line train said she believes her son suffered a mental breakdown.
