The tragedy of school shootings has repeated itself once again. A 15-year-old student opened fire at a high school in Oxford Township, Michigan on Nov. 30 with a semi-automatic weapon. The young man fired between 15 and 20 shots and killed three students aged 14, 16 and 17. 

According to authorities, eight other people were wounded, including other students and teachers, some of whom are in serious condition. 

The young man, who according to initial investigations acted by himself, was arrested without resistance at the scene. 

It was learned that in recent weeks the Oxford Township school authorities were investigating a possible shooting at the school after some acts of vandalism. 

Some parents even revealed to the media that some young people had been talking about rumors of a shooting at the school in recent days. 

That is why they are also investigating clues on social media that may give more details about the reasons behind the shooting that has a small community of 22,000 people 30 miles from Detroit in mourning. 

"My heart goes out to the families enduring the unimaginable pain of losing a loved one," President Joe Biden said during an event in Minnesota.

Michigan Governor Gretchen Whitmer said in a statement: "Gun violence is a public health crisis that claims lives every day. We have the tools to reduce gun violence in Michigan. This is the time to come together and help our children feel safe at school."

This new shooting, and others that occurred in recent days during Thanksgiving celebrations revive the debate around gun control in the country. 

In the state of Michigan alone, 50 bills have been introduced this year to reform gun control laws, and none have made it past debates. In this regard, Whitmer noted that it's "too early to talk about policies that might need to change as a result of this."
