A Fort Worth police officer has been charged in connection with the brutal murder of Atatiana Jefferson, an unarmed Black woman.

The arrest came just hours after Aaron Dean tendered his resignation from the police force. Interim Police Chief Ed Kraus said during a press conference earlier that he intended to end Dean's employment, but Dean got in there first.

Dean allegedly gunned down Atatiani in her own home while she was babysitting her 8-year-old nephew. She was playing video games with him when a concerned neighbor called the cops because her door was left open at night.

Aaron Dean was booked into the Tarrant County Jail and charged with murder. His bail has been set at $200,000.

"We need to see this through to a vigorous prosecution & appropriate sentencing," Jefferson's family attorney Lee Merritt tweeted following the arrest. "The City of Fort Worth has much work to do to reform a brutal culture of policing."
