It was around dismissal time on a routine school day at Marjory Stoneman Douglas High School when the horror began.
A 19-year-old gunman walked onto the campus of the school in Parkland, Florida, armed with what police say was a military-style semi-automatic rifle and countless magazines, and killed at least 17 people.
It was the latest mass shooting in the United States, and shows that the gun violence epidemic can strike anywhere: Last year, Parkland, a Fort Lauderdale suburb, was named the safest city in Florida by The National Council for Home Safety and Security, a trade association.
The suspect, Nikolas Cruz, 19, is in custody and is being held without bond. He has been charged with 17 counts of premeditated murder, and has not yet entered a plea. He is a former student of the school who got expelled for disciplinary reasons, authorities have said.
Here are names, photos and tributes to those killed in a horrific mass shooting.
Luke Hoyer, 15
15-year-old Luke Hoyer will be remembered as a “happy-go-lucky” teenager who loved basketball and most of all, his two older siblings and parents, his aunt tells PEOPLE.
“He was really laid back,” aunt Joan Cox, who saw him over Christmas in South Carolina, says. “He didn’t get upset. He was always smiling, was so sweet and such a good boy.”
His mother, Gena Hoyer, is in disbelief that the last time she’d ever see her son was when she dropped off him at school on Wednesday, according to Cox.
“We’re all just devastated,” says Cox. “We loved him so much.”
Aaron Feis, 37
Aaron Feis, a well-liked assistant football coach and campus security monitor was killed protecting students.
“He would do it again in a heartbeat,” says his brother, Raymond Feis. His sister, Johanna Feis, adds, “Everything he did that day was in character for him.”
Says his longtime friend, Dan Maurer:“He dealt with hundreds of kids every single year. I never heard a mean thing come out of his mouth. Big guy, big heart – and his heart was so much bigger.”
Alyssa Alhadeff, 14
In a post to Facebook, Alyssa Alhadeff’s mother, Lori Alhadeff, confirmed her daughter “was killed today by a horrific act of violence.”
The grieving mother remembered Alyssa as “a talented soccer player” who was “so smart” and had “an amazing personality.”
She added the teen was an “incredible creative writer and all she had to offer the world was love. She believed in people for being so honest.”
Jaime Guttenberg, 14
Jaime Guttenberg’s father took to Facebook to write about the devastation that has hit their family after finding out their daughter was murdered.
“My heart is broken,” Fred Guttenberg wrote. “Yesterday, Jennifer Bloom Guttenberg and I lost our baby girl to a violent shooting at her school.”
Their son, Jesse, who also attends the school, survived the shooting with no injuries.
“I am broken as I write this trying to figure out how my family get’s through this,” Fred Guttenberg added. “We appreciate all of the calls and the messages and we apologize for not reacting to everyone individually.”
Martin Duque, 14
Like so many others, Martin Duque’s family spent the hours after the shooting frantically searching for their relative.
“If you hear anything about him, just please let me know,” Martin’s older brother, Miguel Duque, pleaded with friends on a video uploaded to Instagram last night. “I would really appreciate that.”
At around 4 a.m., Miguel shared news of his little brother’s death.
“Sadly, he’s not with us anymore. He’s in a better place. He’s with the Lord,” Miguel says in another video.
Martin was a freshman at the school. He’s described as being funny and outgoing by his family on a GoFundMe page set up to help pay for funeral expenses.
“He was sweet and caring and loved by all his family,” Miguel writes on the GoFundMe page. “Most of all he was my baby brother.”

Scott Beigel, 35
Scott Beigel, originally from Long Island, also died in Wednesday’s senseless shooting. The 35-year-old is being hailed as a hero; Stoneman Douglas students have said in interviews he provided refuge to numerous students during the violence.

“He was only one call away,” he said.
Cara Loughran, 14
Hours after the shooting, Cara’s mother, Denise Loughran, reunited with Liam, who survived, but was unable to find Cara, according to the Washington Post.

A friend of Wang’s told his cousin, Lin Chen, that he held a door to let students out of the school before him.
“He is so brave. He is the person who is genuinely kind to everyone. He doesn’t care about popularity. He always liked to cheer people up,” Chen told the news outlet. “He is like the big brother everyone wished they had.”
