Ice Cube is speaking out against the white Fort Worth, Texas police officer responsible for shooting and killing an unarmed black woman, Atatiana Jefferson, through a window in her home.

In a series of tweets, the N.W.A legend called Officer Aaron Dean an “animal” and demanded murder charges.

“We need Murder charges and prison time for this animal,” he wrote on Monday (October 14).

Once those charges were filed against Dean later that day, Cube then insisted a conviction was in order.

“Now we need a conviction with no hugs from the judge,” he tweeted on Monday (October 14).

According to CNN, Dean was arrested around 6 p.m. CDT on Monday (October 14) and posted bail roughly three hours later. He was being held on a $200,000 bond.

Attorney for Jefferson’s family, Lee Merritt, tweeted,”The family of Atatiana Jefferson is relieved that Aaron Dean has been arrested & charged with murder. We need to see this through to a vigorous prosecution & appropriate sentencing. The City of Fort Worth has much work to do to reform a brutal culture of policing.”

Jefferson’s brother Adarius Carr told CNN, “He did get what I wanted him to get, and this is only the start. There’s no way this is enough. We know this is a good step in the direction where we want to go, but it’s definitely not the end.”

Interim Police Chief Ed Kraus said Dean was served a written administrative complaint on Sunday (October 13), placed on detached duty and stripped of his badge and firearm. He resigned the following day.

“My intent was to meet with him today to terminate his employment with the Fort Worth Police Department,” Kraus said. “However, the officer tendered his resignation this morning before we met.”

Kraus also explained had Dean not resigned, he would have been fired for several policy violations, including the department’s use of force and de-escalation policies, and unprofessional conduct.

Jefferson was killed on Saturday (October 12) while babysitting her 8-year-old nephew. Dean arrived at her home after a neighbor called a non-emergency line to report her home’s front door had been left open.
