The Glendale Police Department has released body-camera footage of a police officer who resigned after an internal investigation found he used excessive force during an incident in June.

Officer Joshua Carroll resigned from his position on August 31 after he beat David Dulaney so badly that a pool of blood formed on the ground around Dulaney’s head. 

KTAR News first reported that investigators determined Carroll violated department policy by using excessive force and recommended he be fired, but Carroll opted to resign instead. 

The incident happened on June 13, 2019. Police say they received a report of a man sleeping in a car at an apartment complex near Peoria and 43rd avenues.

When Carroll showed up to investigate, Dulaney said he was waiting for a friend and refused to provide his last name or date of birth. Dulaney then started his vehicle, prompting Carroll to pull Dulaney out of the car and use his stun gun.

As the bodycam video shows, Carroll then used the stun gun to assault Dulaney in the back of the head, causing him to bleed profusely. He later required staples to seal his head wound, police said. 

Warning: the footage is extremely graphic and includes explicit language

According to police documents, Carroll told his sergeant that he repeatedly hit Dulaney with the taser, even though Dulaney said “You’re hurting me.”

“I am extremely disappointed in the actions of this former employee,” Glendale Interim Chief of Police Chris Briggs said in a statement.

An internal review panel ruled Carroll was justified in using his taser, using a control hold and striking Dulaney’s head with his hand, but not in striking him in the head with his taser.

Recommending Carroll’s firing, a Glendale police commander wrote that “Officer Carroll has a pattern of discipline involving poor decision making that has escalated to a point that I no longer have confidence in his ability during routine contacts and stressful situations.”
