Jason Van Dyke
U.S. attorney John Lausch said he will not prosecute Van Dyke, who was released from prison earlier this year after serving less than half his sentence.
Chicago cop now being charged with murder had 20 previous complaints filed against him. He was never penalized.
Van Dyke served about half of his sentence for killing the Black teen in 2014. A growing number of voices are calling for him to face federal charges.
Jason Lee Van Dyke allegedly used the Proud Boys street gang to keep watch on a man he wanted to kill, according to authorities in newly released documents.
WHAT'S HAPPENING
After months of threats, slurs and lawsuits, the State Bar of Texas is disciplining Van Dyke.
Former Chicago police officer Jason Van Dyke was sentenced in January to 81 months in prison for the murder of 17-year-old Laquan McDonald.
The extremist gang's leader is trying to bail, its members are in jail, and the FBI is on its tail.
A jury also convicted the cop of 16 counts of aggravated battery -- one for each time he shot the teenager.
The Chicago police officer was on the witness stand to tell his version of what happened the night he emptied his 9 mm into McDonald.
Jason Van Dyke has a long list of infractions. Now he faces charges for allegedly lying to police.
