Police say newly released footage of Wade Michael Page's shooting rampage at a Wisconsin Sikh temple last month reveals Page shot the first officer he encountered 15 times before he was taken down by a second officer.

According to WISN-TV, Oak Creek Police released dashboard camera footage from Page's encounters with Lt. Brian Murphy and Officer Sam Lenda.

Authorities said more footage from Page's Aug. 5 attack will be released after it is determined whether Page, who had apparently fallen in with the white supremacist movement, had help before the attack, in which he killed six people and injured Murphy and four others before killing himself.

In the video, police said, Murphy can be seen checking on two of Page's earlier victims before stepping across the temple parking lot and engaging Page. Murphy is then hit in the throat and goes down. Page circles around the parking lot and continues shooting Murphy from about 10 feet away before Lenda arrived in his own patrol car.

"He was firing at me," Lenda said at a press conference Monday. "One round of the rounds he was firing at me hit the squad [car] right above the steering wheel and it went into the headrest ... once he started firing on me, then I returned fire."

Lenda fired six rounds of his own with an AR 15 assault rifle, hitting Page in the stomach and dropping him.

The Milwaukee Journal-Sentinel reported that Lenda has resumed his duties after a review of his and Murphy's actions by the Milwaukee County District Attorney's office said they were justified.

CNN posted video of the shooting Tuesday morning, which can be seen below.
