FORT WORTH, Texas (CBSDFW.COM) — The murder trial for former Fort Worth police officer Aaron Dean is now in its fifth day.
Dean is accused of intentionally shooting and killing 28-year-old Atatiana Jefferson inside her home back in October 2019.
Dean himself took the stand on day four, and didn't waste any time addressing the jury.
"This jury needs to hear from me and hear the truth."
Following that statement, the 38-year-old briefly described his life growing up in Arlington. He also talked about his professional life prior to joining law enforcement. He formerly worked as an engineer at a commercial refrigerator plant in the area.
At the age of 32, he started the application process to become an officer with the Fort Worth Police Department. In August of 2017, he was accepted to the police academy.
The jury of 12 will make the decision on whether Dean remains free or spends up to life in prison.
The trial will be streamed live everyday on CBS News Dallas-Fort Worth.
