Four Minneapolis police officers were fired Tuesday after a 10-minute viral video surfaced of one of the officers holding his knee to a man’s neck as the man struggled to breathe one day earlier. The man, identified by attorney Benjamin Crump as George Floyd, was pronounced dead after the incident. Authorities, including the FBI, are investigating the incident, which sparked protests across the city. Here's what we know so far about Floyd: 1. The 46-year-old St. Louis Park resident was a security guard at Conga Latin Bistro in Minneapolis. According to the Star Tribune, Floyd had worked at the restaurant for five years and rented a home from the restaurant’s owner, Jovanni Thunstrom. In a Facebook post Tuesday, Thunstrom described Floyd, who grew up in Houston, as not only his employee but also 'a very good friend.' 'Watching this video makes tears come out,' Thunstrom wrote. 'My body is full of emotions, of questions without answer.' He also told the Star Tribune that Floyd 'was family.' 'His co-workers and friends loved him,' Thunstrom said. 2. One restaurant patron described Floyd, who was known as 'Big Floyd,' as a 'gentle giant.' Conga customer Jessi Zendejas said in a Facebook post that the security guard 'loved his hugs from his regulars,' according to the Star Tribune. '[He] would be mad if you didn't stop to greet him because he honestly loved seeing everyone and watching everyone have fun,' Zendejas wrote on social media. Thunstrom echoed the sentiment in an interview with KSTP. 'He wanted me to teach him how to Bachata dance, and I gave up because I couldn't turn him because he was 6-foot-6,' Thunstrom told the news outlet, adding that Floyd 'wasn't the bad guy.' 'He had other problems, but we all have problems,' Thunstrom told KSTP. 'He wasn't the type that was aggressive, disrespectful. He was a very calm, nice guy. I want people to remember him that way.' 3. Floyd's former partner, Christina Dawson, paid tribute to him in a Facebook post. 'They really killed my baby!!' wrote Dawson, who told the Star Tribune that the pair had stayed friends after their split. 'I don't even know what to do, y'all,' she continued. 'This is not real!' 4. Minneapolis police said Floyd resisted arrest after officers responded to a forgery call Monday involving a suspect who 'appeared to be under the influence.' In a statement, the department said officers arrived to find Floyd in his car and asked him to step out. 'After he got out, he physically resisted officers,' the statement continued. 'Officers were able to get the suspect into handcuffs and noted he appeared to be suffering medical distress. Officers called for an ambulance. He was transported to Hennepin County Medical Center by ambulance, where he died a short time later. At no time were weapons of any type used by anyone involved in this incident.'

Attorney Tom Kelly told The Associated Press on Tuesday that Chauvin is his client but did not release any additional details. Earlier Tuesday, Chauvin and the three other officers involved in the incident were fired from the Police Department, officials said. “This is the right call,” Minneapolis Mayor Jacob Frey tweeted. State and federal authorities are now investigating the incident, and Minneapolis police are conducting their own internal investigation, the AP reported.
