VALDOSTA – Eyewitness video captures the chilling moments before a Valdosta man was shot and killed by police.

The Georgia Bureau of Investigation announced Thursday that the man, identified as Johnathan Lozano-Murillo, had died from his injuries.

The Georgia Bureau of Investigation says Valdosta officer Alyssa Shirey was called to a child custody dispute involving Lozano-Murillo at around 6 pm, in the 1600 block of Fresno Street.

Investigators say the woman involved in the dispute with Lozano-Murillo arrived at the scene, and he attacked her. Officer Shirey stepped in, trying to protect the woman from Lozano, who was striking the woman.

According to the GBI, at some point Lozano-Murillo drew a knife and went after the officer. She tried to use a taser, but it didn’t work. The GBI says Lozano-Murillo kept advancing toward Officer Shirey when she shot him.

He was taken by ambulance to a local hospital where he later died.

Cellphone video taken by a witness at the scene shows the tense moments leading up to the shooting and then the gunshots ringing out. Some of the video footage may be disturbing.

The AP reports that GBI spokeswoman Nelly Miles said the officer is white and Lozano-Murillo was Hispanic.

GBI says its agents interviewed witnesses, processed the scene and collected evidence throughout the night and are continuing with their investigation.
