One day after a suburban Cleveland high school student opened fire on other students, three children have died from their injuries and two more are wounded.

"The cause and manner of death of this case are under ongoing investigation and will be released upon completion," said Cuyahoga County Medical Examiner's office administrator, Hugh Shannon.

Five students at Chardon High School were injured Monday morning when a student-suspect identified as T.J. Lane began shooting. Law enforcement sources have reported that Lane said he was a victim of bullying.

Days after Lane told his friends he was going to bring a gun to school, three students are dead. This is not the first instance of deaths resulting from bullying, however. Just last month, 15-year-old Amanda Cummings — who was bullied in person and on Facebook — jumped in front of a southbound Metropolitan Transportation Authority bus, carrying a suicide note in her pocket. Over a year prior, 15-year-old Phoebe Prince — who was verbally harassed and physically abused by an alleged group of 9 girls — hung herself in a stairway.

When Is Bullying a Civil Rights Issue?

Schools that receive federal funding (including colleges and universities) are required by federal law to address discrimination on a number of different personal characteristics. Bullying may be a civil rights violation when someone’s race, color, national origin, gender, sexual orientation or disability is discriminated against.

What to Do When You Are Being Bullied?

If you are being bullied, don’t take the abuse:

—Tell them to stop.  

—Walk away. Do not let them get to you. If you walk away or ignore them, they will not feel the satisfaction of getting a rise out of you. 

—Protect yourself. Sometimes you cannot walk away. If you are being physically hurt, protect yourself so that you can get away. 

—Tell an adult you trust. Talking to someone could help you figure out the best ways to deal with the problem. In some cases, adults need to get involved for the bullying to stop. 

—Find a safe place. Go somewhere that you feel safe and secure, like the school library, a favorite teacher’s classroom, or the office.

—Stick together. Stay with a group or individuals that you trust. 

—Find opportunities to make new friends. Explore your interests and join school or community activities such as sports, drama, or art. Volunteer or participate in community service.

What to Do When Bullying Continues or Gets Worse?
 
If someone is at immediate risk of harm because of bullying, call 9-1-1 immediately. If you know someone who is feeling suicidal because of bullying, contact the suicide prevention hotline at 1-800-273-TALK (8255).

I’m a Parent, What Do I Do When Bullying Gets Worse and My Child Needs Additional Help?

If your child’s teacher is not keeping your child safe, contact the local school administration (principal or superintendent). If your school is not keeping your child safe, contact the state school department. If your child is bullied because of their race, ethnicity, gender, sexual orientation or disability and local help is not working, contact the U.S. Department of Education’s Office on Civil Rights.
