The Marjory Stoneman Douglas High School massacre continues to shock the nation. Over 17 people lost their lives during the mass shooting.

Josh Gad In Mourning

Actor Josh Gad knew one of the people that were murdered by the alleged shooter, 19-year-old Nikolas Cruz, who was expelled from the school.

"Last night, I received a text while I slept that our friend's son passed away from his gunshot wound. My grief for this family and the many others knows no bounds. I'm so sorry this happened. I'm so sorry our leaders are worthless. I'm so sorry we are bound to repeat this again," wrote Gad in a Twitter statement.

Josh Gad Takes Action

Following his Twitter post, the Frozen and Murder on the Orient Express actor made a solemn vow to make sure that his friend's son's death would not be in vain. Gad vowed to support anti-National Rifle Association candidates and added that he would educate himself on why people refused to do anything about gun laws and decided to push them into retirement. He also challenged his Twitter followers and the world to see what actions they would take to change the world. 

"I am going to be here as a voice of reason and walk proudly and tall through the echoing winds of madness as we continue to demand action in a familiar sea of inaction," wrote Gad in another Twitter statement.

Twitter Answers The Call

Several of Gad's followers answered the call and revealed what they would do to challenge the gun violence.

"Today I started a non-profit that is going to work to humanize the issue of gun violence and through the apathy Americans and politicians currently have around this issue," wrote a Twitter user.

"I am ready to march...I am ready to take to the streets. I'm tired of writing to my Congress and Senate reps, I want to march shoulder to shoulder in unity with people who want change," wrote another Twitter user.

Other Celebrities Rally For Change

Gad was not the only celebrity to raise their concern regarding the school shooting. While other celebrities such as Kevin Love, Mike Tyson, and Fifth Harmony decided to send their thoughts and prayers, Ellen DeGeneres and Bette Milder lead the charge as they called for the end of the school shooting epidemic.
