Police said the gunman who opened fire inside a library at Florida State University early Thursday was in a "state of crisis" at the time of the shooting.
The gunman who was shot dead by police was identified by law enforcement officials as Myron May, a lawyer who graduated from the school.
Police said May injured three students before being shot dead at the Strozier Library. Two of the wounded students were admitted to Tallahassee Memorial HealthCare hospital and the third was treated and released at the scene, police and a hospital spokeswoman confirmed.
At a news conference Thursday afternoon, police said May was struggling psychologically and emotionally. May feared government targeting and expressed these concerns in his journal, police said. Yet, police said it was unknown why May attacked or why he targeted Strozier library.
May, who was born in Dayton, Ohio, moved to Florida as a teenager, police said. He graduated from FSU in 2005 and later from Texas Tech Law School in 2009, police said. After practicing law in Texas and New Mexico, May moved back to Florida just three weeks ago, police said.
Police said May had two previous encounters with law enforcement. In 2002, he was suspected of using marijuana, and in 2003 he was the victim of a vehicle burglary, police said.
At a news conference Thursday morning, police called the shooting an "isolated incident" and said May had acted alone.

Florida Gov. Rick Scott said he hoped to visit the victims at the hospital later Thursday and said authorities were still investigating the shooting.
"We still have a lot of questions that are unanswered," Scott told reporters at a news conference.
Amid the chaos, students immediately took to social media with messages of concern and prayers.
“Please say a prayer for us. We’re stuck in a library with a shooter in the building,” tweeted a person whose profile says he’s a student at FSU.
Another tweet came from the father of a FSU student who took a screen shot of her text message to him, stating, “There’s a man with a gun in the library. I love you.”
Jason Derfuss, a 21-year-old humanities student at FSU told NBC News his backpack full of books stopped a bullet from hitting him during the rampage. Derfuss only realized hours later the gunman had tried to shoot him after he discovered a bullet lodged in "The Oxford Context of Wyclif’s Thought."
"There is no way I should be alive," Derfuss told NBC News. "Literally, those books saved my life."
The campus scare began when police at Florida State University responded to a "dangerous situation" at the library around 12:30 a.m. ET Thursday, as a witness reported gunshots. A campus telephone alert urged people to take shelter in a nearby building and stay away from "doors and windows."
When officers arrived, they commanded May to drop his weapon, Tallahassee Police Department spokesman David Northway said. Police said May was using a .380 semi-automatic handgun and had additional ammunition in his pockets. May fired a round at police, who responded with shots, killing the suspect, police said.
Officers searched the area and found three victims suffering from gunshot wounds, police said.
According to officials, May never made it past library security and only shot from the library lobby. One victim was shot in the library lobby and the two others were shot outside the lobby area, police said.
All three victims were immediately given treatment, police said. Two victims were taken to Tallahassee Memorial HealthCare hospital. One was in critical condition and the other was in stable condition, officials said.
One of the victims was identified as Nathan Scott, according to a statement released by the hospital. Scott was shot in the leg and is recovering with the support of his family who has asked for privacy at this time, the hospital said.
Police said the library was packed with between 300 and 400 students at the time of the shooting.
Steven Dawson, 19, a freshman biology major said he was studying on the library's third floor at the time of the incident. Dawson told NBC News that shortly after 12:30 a.m. ET someone started shouting about a gunmen in the building. "Everyone just dropped everything and started running," Dawson said.
The university announced on Twitter early Thursday that the lockdown had been lifted and the area was secured.
FSU President John Thrasher said there will be increased security measures and a greater law enforcement presence on campus Thursday.
"The Florida State University community is extremely saddened by the shootings that took place early this morning at Strozier Library, in the very heart of campus, and our thoughts and prayers are with the families and loved ones of all those who have been affected," Thrasher said in a statement.
Classes were canceled for Thursday but the campus will be open, the university announced. Strozier Library will be closed until further notice. Meanwhile, students were gathering for prayer vigils on campus throughout the day.
Thrasher said counseling would be provided for students, faculty and staff.
"The three students who have been injured are our highest priority followed by the needs of our greater university community," Thrasher said. "We will do everything possible to assist with their recovery."
