Last night, a black man in California suddenly drove into a number of innocent people on the side of the road, resulting in the injury of 8 people, including a 13-year-old teenager, and many of them were seriously injured.
But what is even more surprising is the discovery of the official preliminary investigation in the United States and the media excavation of the background of the murderer...

According to cbs news network, the case took place in Sunnyvale, California, and local police have identified the killer as Isaiah J. Peoples, a 34-year-old local.
During police interrogation, he admitted that he had deliberately driven his car into a passerby. But police don't consider the case linked to terrorism because Peppers is not affiliated with any terrorist group.

However, CBS's interview with Peppers' family gave some surprising news. One of his family members said Mr. Peppers was an U.S. military veteran who had served in Afghanistan and suffered from post-traumatic stress disorder (PTSD) there.
The family member also said That Peppers did not take psychotropic drugs prescribed to him by doctors, so he often behaved strangely, such as singing Christian songs out loud in the corner.
In fact, after he hit someone with his car, witnesses heard Pipers muttering "I love Jesus" as he got out of the car.
In addition, according to the Associated Press, Peppers' mother said that his son is a "model citizen" and would never deliberately drive a car to hit someone unless it is a ptsd illness. The mother also said Peppers was also discharged from the army because of PTSD.
At present, the local police are still investigating Pippers' motives and are assessing whether the case requires the intervention of the US federal government.
