(PEORIA, Ill.) -- The trial began on Wednesday of Sean Grayson, the former sheriff's deputy, who was charged with first-degree murder in connection with the July 2024 fatal shooting of Sonya Massey, a Black woman who called 911 to report a possible intruder at her home in Springfield, Illinois.
The Sangamon County deputy was charged with a total of three counts in connection with Massey's death -- first-degree murder, aggravated battery with a firearm and official misconduct.
The trial began with jury selection on Monday, where a panel of 12 jurors was seated, according to ABC News' affiliate in Springfield, WICS. The process took more than five hours and ended with a jury made up of nine white women, one Black man and two white men, as well as two white men and one white woman selected as alternate jurors.
Body camera footage of the incident released by Illinois State Police on July 22, 2024 shows Massey telling the two responding deputies, "Please, don't hurt me," once she answered their knocks on her door.
Massey died from a gunshot wound to her head, according to an autopsy report released in July 2024, Sangamon County Coroner Jim Allmon confirmed to ABC News.
Grayson said he feared for his life during his encounter with Massey, according to documents released by the Sangamon County Sheriff's Office in August 2024.
Crump said that Massey struggled with her mental health and body camera footage released in Sept. 2024 shows her interacting with officers on July 5 -- 16 hours before she was fatally shot -- after her mother called 911 to report that her daughter was having a mental health episode.
