BREAKING: Charge against Derek Chauvin increased to second-degree murder, three more cops charged

The three former Minneapolis police officers will be criminally charged relating to the murder of George Floyd, according to a tweet from former presidential candidate and Minnesota Senator Amy Klobuchar.

Derek Chauvin, the officer who was formerly charged with third-degree murder, will now be charged with second-degree murder, the tweet also states.

"Minnesota Attorney General Keith Ellison is increasing charges against Derek Chauvin to second-degree in George Floyd’s murder and also charging other 3 officers. This is another important step for justice," said Klobuchar in her tweet on Wednesday.

The charges laid against the three other officers; Tou Thao, J. Alexander Kueng and Thomas Lane, will likely be for aiding in a second-degree murder.

Those three officers allegedly watched as Chauvin kneeled on Floyd's head and neck, eventually killing him.

The Floyd family has called for Chauvin to be charged with first-degree murder. A second-degree charge has a state maximum sentence of 40 years upon conviction, compared to 25 for a third-degree murder, reports CNBC.

An autopsy into Floyd's death concluded that his death was a homicide from "cardiopulmonary arrest." Underlying conditions were also a contributing factor to his death, along with potential drug intoxication.

In all, Chauvin had his neck on Floyd's neck for a total of eight minutes and 46 seconds, along with three additional minutes after Floyd became unresponsive,
