Alleged shooter identified as James T. Hodgkinson: NBC News
Hodgkinson was a 66-year-old man from Belleville, Illinois, which is in the southern part of the state near St. Louis, NBC News reported, citing federal law enforcement officials.
Court records examined by NBC News show that he had a history of arrests and was charged in 2006 with assaulting his girlfriend. Police recovered a shotgun from Hodgkinson following that arrest.
More recently, police responded to a "shots fired" call in Hodgkinson's hometown in March of this year. Hodgkinson was found with a weapon in his possession and a valid Illinois firearms license. The police report indicates that he was advised not to fire his weapon in an area with homes nearby.

The shooting took place as a GOP congressional baseball team was practicing in Alexandria, Virginia, ahead of a charity game between Republicans and Democrats scheduled for Thursday.
Police say it is too early to determine a motive in the shooting.
A Facebook page for a user named James Hodgkinson from Belleville, Illinois, contained many posts that mocked President Donald Trump and were supportive of former presidential candidate Senator Bernie Sanders.
In a statement, Sanders condemned the shooting.
"I have just been informed that the alleged shooter at the Republican baseball practice is someone who apparently volunteered on my presidential campaign," he said. "I am sickened by this despicable act. Let me be as clear as I can be. Violence of any kind is unacceptable in our society and I condemn this action in the strongest possible terms."
GOP Representatives Ron DeSantis and Jeff Duncan both said a man police identified as Hodgkinson spoke to them just before the shooting and asked whether the people at the baseball practice were Republicans or Democrats.
The shooter wounded multiple people early Wednesday, including Majority Whip Rep. Steve Scalise, who was shot in the hip, and a staff member from the office of Rep. Roger Williams, R-Texas.
Scalise is undergoing surgery.
Rep. Rand Paul, R.-Ky., and Rep. Mo Brooks, R.-Ala., who were both at the baseball field, described the weapon used by the shooter as a rifle. Paul said he heard a first, "isolated" shot followed by a "rapid succession" of five to 10 shots.
Capitol Police and Alexandria police officers who responded to the scene exchanged fire with the shooter, according to Capitol Police Chief Matthew Verderosa.
