He Bought an AR-15-Style Rifle, Commonly Used in Mass Shootings

In Florida, it is easier purchase an AR-15-style weapon than a handgun. When a person turns 18, it is legal to buy a semiautomiac rifle, but they must wait until 21 to buy a handgun, notes The New York Times.

This is why it is common to see mass shooters use it, even outside of Florida. The National Rifle Association says it is the most popular rifle in the U.S. It was used at Newtown, San Bernardino, Las Vegas and in other shootings.

Peter J. Forcelli, the special agent in charge for the Bureau of Alcohol, Tobacco, Firearms and Explosives in Miami, confirmed that no laws were broken when Cruz bought his weapon.

Cruz bought it before moving into the house of a friend's family, but they required him to keep it in a lockbox. The family's attorney, Jim Lewis, told the Times that they encouraged Cruz to go to adult education classes, but he refused to go the day of the shooting.

Cruz Was Abusive Towards his Ex-Girlfriend

Cruz was expelled from Marjory Stoneman Douglas High School last year after fighting with his ex-girlfriend's new boyfriend.

"The reason he got expelled was because he was fighting with his ex-girlfriend's new boyfriend," Connor Dietrich, a 17-year-old junior, told the New York Post. "He stalked her and threatened her," Dietrich recalled.

"He was like, 'I'm going to kill you,' and he would say awful things to her and harass her to the point I would walk her to the bus just to make sure she was OK. We all made sure she was never alone."

Sophia Serino told the Post Cruz talked about shootings before, but a friend talked him down.

"It wasn't something that was spontaneous. I think he really planned this," Serino said.

Neighbors Said His Mother Called Police to Keep Cruz "In Line"

Neighbors told The New York Times they believed Cruz was a troubled boy. Helen Pasciolla said his mother often called sheriff's deputies to keep her son "in line." Craig Koblitz, who lives across the street, said other neighbors suspected he robbed a house a few years ago. Six years ago, Koblitz saw Cruz scooping fish from a pond, showing no guilt after being caught stealing.

"He had emotional problems and I believe he was diagnosed with autism," Gold told the Times. "He had trouble controlling his temper. He broke things. He would do that sometimes at our house when he lost his temper. But he was always very apologetic afterwards.

"He would sometimes be hitting his head and covering his ears. One time, I sent him home because he was misbehaving at our house and he took a golf club and smashed one of my trailers." Gold also said Cruz's mother meant everything to him." Gold added.

"His mother was his entire life and when he lost her, I believe that was it for the boy's peace of mind."

Cruz Shot at Chickens and Tortured Animals

Cruz's neighbors also recall that he shot chickens with his pellet gun. He also tortured other animals, turning his god loose on potbellty pigs, according to the Wall Street Journal.

"He would come in with combat boots on and camouflage clothing all the time," said Tony Elias, who was a member of the Army Junior Reserve Officer Training Corps with Cruz. "He said he enjoyed killing small animals and he was really fascinated by guns. It was kind of an unhealthy obsession."

Malcolm Roxburgh, a former neighbor, told the Wall Street Journal that Cruz shot at chickens owned by another neighbor. When another neighbor confronted him, he threw an egg at the neighbor's truck. Roxburgh said that when Cruz moved away, everyone was "relieved on this street that they had gone."

Cruz Was Considered a Threat and Could Not Bring a Backpack to School

Jim Gard, a math teacher, told the Miami Herald that Cruz was considered a threat in the past. The school sent out an email warning teachers about Cruz's threats to other teenagers.

One student told the paper Cruz once brought bullet casings to school and was punished. Gard said Cruz was not allowed to bring a backpack to school.

"We were told last year that he wasn't allowed on campus with a backpack on him," Gard said. "There were problems with him last year threatening students, and I guess he was asked to leave campus."

Gard kept six kids locked in his classroom during the shooting.

Students Say Cruz Stalked Another Girl at School

Several students told Jim Gard that Cruz became interested with another girl at the high school "to the point of stalking her," he told the New York Times.

Gard described Cruz as "quiet and not disruptive," but he also told the Times about the warnings teachers received from administrators.

"He was always to himself and never tried to associate himself with anyone," student Brandon Minoff told CNN. "As far as I know, he didn't have any friends."

Cruz Stopped Going to a Mental Health Clinic

Broward County Mayor Beam Furr told CNN that Cruz was getting treatment at a mental health clinic, but he stopped going over a year ago.

"It wasn't like there wasn't concern for him," Furr told CNN. "We try to keep our eyes out on those kids who aren't connected. … In this case, we didn't find a way to connect with this kid."

"You keep your eyes on those kids who become disconnected — you know, they're out on the fringes. And as a teacher, you try to bring them into the fold, so to speak, in one way or another," Furr told WBUR. "It's part of our mission to make sure that kids become part of the overall community — and when one gets away, it's just sad."

Despite his past at a mental facility, he still passed a background check that allowed him to buy his weapon legally.

All He Would Talk About Is Guns, Knives and Hunting, a Former Classmate Said

Joshua Charo, a former classmate, told the Miami Herald he was not shocked to hear about Cruz, considering his past experiences with him.

"All he would talk about is guns, knives and hunting," Charo said. "I can't say I was shocked. From past experiences, he seemed like the kind of kid who would do something like this."

"Our investigators began dissecting social media," Broward County Sheriff Scott Israel told the media Wednesday. "Some of the things that come to mind are very, very disturbing."
