Video released a year after McDonald's death showed he wasn't threatening Van Dyke before the officer shot him 16 times at close range.
"The Department and its outside counsel have carefully reviewed the reports and supporting documents, videos, and other evidence and will accept the [Inspector General's] recommendation to submit seven of the officers to the Police Board for separation based upon Rule 14 allegations outlined in the OIG's report", the department said in a statement.
Chicago Police Superintendent Eddie Johnson recommended Thursday that seven officers who lied during the investigation of the Laquan McDonald shooting be fired. The process typically takes about seven months, so any decision to fire the officers is not likely until next year.
The decision comes after the city's inspector general delivered a report this week on the shooting that called for the officers to be fired.
Two of the 10 officers who were recommended for firing retired this week, according to media reports.
"It is my belief that through these challenges we can take the lessons learned to become a better department and in turn, give you additional resources to do your jobs effectively", Johnson added. Kane County State's Attorney Joseph McMahon was given the case on August 4. The next year, when a judge forced the city to release the explosive police video that documented the shooting, Van Dyke was charged with first-degree murder. Matt Topic, the attorney with Loevy & Loevy who fought in court to release the McDonald shooting video, applauded Johnson's decision. He has been suspended without pay, a Chicago Police Department spokesperson told ABC News.
The FBI previously launched its own investigation into Laquan's death. According to ABS, they quickly offered the McDonald family a $5 million settlement, even before they filed a lawsuit.
The teen was shot and killed on October 20, 2014, after police were called to a trucking yard to investigate a spate of attempted auto burglaries. Prosecutors say the 3-inch blade was found folded into the handle.
Officers attempted to surround Laquan, but he slashed one of the tires of a squad auto and began jogging away, according to police.
Questions have remained since McDonald's death almost two years ago about what discipline could follow, after suggestions that the teenager lunged at police was shown to be untrue by the video footage. An autopsy later revealed Laquan had PCP in his body.
