The day before the fatal police shooting of Sonya Massey in Springfield, Ill., her mother called 911 and asked for help, saying that her daughter was having a mental breakdown and asking the police to recognize her vulnerable condition, according to call recordings released by county officials in Illinois on Wednesday.

In a phone call made around 9 a.m. on July 5, Donna Massey told the dispatcher: “I don’t want you guys to hurt her, please.”

Sonya Massey, a 36-year-old Black woman, called the police for help the next day, on July 6, and was fatally shot inside her home by a Sangamon County sheriff’s deputy, Sean Grayson, who is white. Ms. Massey had called emergency services because she believed an intruder had entered her home, prosecutors said. Mr. Grayson, 30, was charged with murder and was fired last month.

Body camera footage from the shooting shows that Mr. Grayson and his partner searched outside of Ms. Massey’s home before they followed her inside. After she provided the officers with her identification, she went to the kitchen to remove a pot of water from the stove. As she was handling the pot, several feet away from the deputies, Ms. Massey said twice to the deputies, “I rebuke you in the name of Jesus.”

Mr. Grayson told Ms. Massey that she “better not,” using expletives and threatened to shoot her in the face. Within seconds, Mr. Grayson drew his gun, ordered Ms. Massey to drop the pot, and fired at least two shots at her, the video shows.

On Wednesday, Sangamon County released 911 call recordings and reports showing that local law enforcement were aware of Ms. Massey’s mental health issues and that she had been in contact with treatment providers before her death. It is not clear if the two deputies who entered her home on the day of the shooting were told that she was having mental health issues.
