Update 06/07/2020 12:39pm:

One of the police officers charged in George Floyd’s murder—Thomas Lane (pictured in the middle above), reportedly had seven convictions prior to being hired as a police officer. 37-year-old Lane was present when Floyd was choked to death by ex-cop Derek Chauvin, and sat there and did nothing while the traumatic incident took place.

It was reported that Lane was only on his fourth full-time shift as a Minneapolis cop when the George Floyd incident went down. Lane reportedly has a long list of criminal charges prior to becoming a cop, along with many traffic violations. Lane was convicted for an incident that went down in 2001. Lane was convicted of damaging property and hit with one count of obstructing legal process.

Currently, Lane is being held on unconditional bail of $1 million or $750,000 with conditions.

The other three officers involved in the murder of George Floyd have been charged and booked as of Wednesday evening. The former officers, Tou Thao, Thomas Lane and J. Alexander Kueng, were charged with aiding and abetting murder. Each of the men had bail set at $1 million according to Hennepin County Jail Records. 

If convicted, all four former officers could receive a maximum 40-year prison sentence. Despite all four officers now being in custody, Minnesota Attorney General Keith Ellison called on the public to remain patient due to the fact that charging and convicting police officers is near-impossible. "I feel a tremendous sense of weight, I feel that this is a very serious moment," said Ellison. "I can tell you I feel no joy in this, but I do feel a tremendous sense of duty and responsibility."

Ellison also explained why the prosecution believed a second-degree murder charge was an easier path toward conviction considering the burden on prosecutors to prove premeditation in a first-degree murder case.

According to the Minneapolis Star Tribune, David Chauvin, the now-former police officer who kneeled on George Floyd's neck until he was unresponsive, will have his charges upgraded to second-degree murder by Attorney General Keith Ellison. The other three officers involved in the incident, Tou Thao, J. Alexander Kueng and Thomas Lane — will also be charged with aiding and abetting second-degree murder. 

This comes after Chauvin was arrested last Friday and charged with third-degree murder and manslaughter. Benjamin Crump, the attorney for Floyd's family, reacted to the news involving the four officers, stating, "This is a bittersweet moment for the family of George Floyd. We are deeply gratified that Attorney General Keith Ellison took decisive action in this case, arresting and charging all the officers involved in George Floyd's death and upgrading the charge against Derek Chauvin to felony second-degree murder."
