Parkland victim's father mourns on Twitter on what would've been daughter's 15th birthday

Jaime Guttenberg would have turned 15 on Friday had a gunman not killed her and 16 others at Marjory Stoneman Douglas High School in Parkland, Florida in February.

On her birthday, her father Fred Guttenberg and family took to Twitter to express their grief over never being able to watch her grow up. The family's also using Twitter as a way to rally for gun safety laws.

In a Twitter DM exchange, Fred told Mashable he needed a place to express his voice and only joined Twitter after his daughter had passed.

"I was not even on Twitter until a few weeks after my daughter died," said Fred. "I decided to join as I felt I needed to express my voice and Twitter became a way for me to speak for Jaime and for all of the victims of preventable gun violence."

His tweets, as well as those from Jaime's family, are heartbreaking.

When asked why he responds to trolls on Twitter who come after him for advocating for gun control, Fred said he thinks about his daughter's final moments.

"Every day, I think of my daughter and the fear and anxiety she had when she was running from a gunman. Words simply do not impact me now," he told Mashable.

Fred's not just passively sharing Jaime's story on social media, he's also using Twitter to talk about the actions he's taking to convince lawmakers to pass gun control.

There are several ways you can still help the Parkland shooting victims, including donating to awareness campaigns like Orange Ribbons for Jaime and fundraisers in honor of other victims, as well. You can make your voice heard on social media, like Fred, tell lawmakers the types of regulations you want them to create, and support the March for Our Lives summer tour, which features students from Marjory Stoneman Douglas High School registering voters and talking about gun reform at stops throughout the U.S.
