The 40-year-old gunman was known to campus police for his behavior because of three phone calls.
First battery charge
On December 7, 2012, two women in a FSU dining room complained that a man had touched her buttocks. The police arrived and identified the man as Beierle, according to a report from the campus police.
"Beierle explained that he accidentally hit several girls but did not grab anyone," the report said.
One victim, however, said the police had definitely grabbed Beierle's butt while a second wife not only acknowledged that Beierle was grabbing the other victim's ass, but also that Beierle had grabbed her buttocks three times in the past few weeks, she said Police with.
Beierle was arrested and charged with two batteries. Records from the county court of Leon County indicate that the case has been dropped.
More than two years later, Beierle drew the attention of campus police when a gym employee saw Beierle talking to himself before following down a volleyball trainer in a gym, a police report said.
The employee at the gym monitored Beierle, who noticed that he was being followed and left, said the employee of the police. On June 17, 2014 Beierle came back and asked the employee to call the police.
Beierle was lying on a couch with his shoes off and telling the police he'd come by to use the bathroom and digest his food.
He was thirty-five years old at the time and told an official that he was an FSU student, but he resisted saying that he was an alumnus who had visited the campus to eat and seek work, according to the report , Beierle said he had not followed anyone, and the report said he should leave.
The officer learned that Beierle was serving a statement of peace in front of the dining room where he was arrested in 2012, the report said.
Trespassing and battery arrests
Three weeks later, a campus policeman recognized Beierle at lunch time when he entered a bathroom in the dining room and confirmed his identity, the report said.
"While waiting for shipment, Beierle pointed out that he would receive a warning about crossing the FSU campus," the interim report said. "I told him he's in an FSU building right now and he guessed he did not know it, Beierle advised me to arrest him now."
The case was settled by "other provisional intervention" according to a search in the records of the county council of Leon County.
The teenager was sitting by the pool alone, sunbathing, as Beierle, a tenant in the complex, sat down next to her and told her she had a "nice butt," the interim report said.
"She thanked him and he offered to put sunscreen on it, she told him no, she did not need it," says the report.
Then he asked her name, she signed up and Beierle "then slapped her butt and grabbed him, then shook him", before leaving the pool area in a hurry, the report said.
The answering officer returned to the complex the next day to watch surveillance videos that confirmed the victim's allegations, the report said. Beierle was charged with a battery, the police said.
According to a record from Leon County, the case was dismissed in May 2017.
Memory of the victims
On Sunday, the Florida State community – including yogis, health professionals, students and faculty – gathered to honor the victims of Friday's shootings.
Maura Binkley was an FSU student who "radiated love for all," her father said, and Nancy Van Vessem was a faculty member who, according to her friends and colleagues, has touched many lives.
The crowd gathered on Langford Green Sunday night to hold battery-powered tea candles flickering under a clouded sky as a small choir sang "Hymn to the Garnet and Gold."
Authorities say it's not clear why Beierle carried out the attack. Investigators have not yet discovered any links between the shooter and the victims or the yoga studio, said Tallahassee police chief Michael DeLeo.
On Saturday, the police searched Beierle's apartment in Deltona and his electronic devices for clues.
Beierle said that as a teenager, he could refer to "this endless wasteland that produces that longing and frustration," the Times reported.
