The Phoenix Police Department released security footage Friday of a shooting rampage that killed two people and wounded several others near 27th Avenue and Dear Valley Road on the night of August 28. 

Police said that Isaiah Steven Williams, 24, left a Phoenix hotel room armed with a semi-automatic rifle when he began firing at bystanders and throwing Molotov cocktails.  

According to authorities, 36-year-old Misael Arevalo and 44-year-old Karla Garzona were killed after Williams opened fire on a white vehicle entering the motel parking lot around 8:30 pm. 

Police said that officers who responded began to fire at Williams when they were met with gunfire as well. One was struck in the shoulder by a bullet and another was hit by shrapnel and injured, according to police.

What the footage shows

In the footage, Williams can be seen leaving his hotel room dressed in dark tactical gear and helmet with his rifle and Molotov cocktail in hand. He quickly reached the parking lot and began to walk around and fire off dozens of shots at buildings and vehicles. 

Williams then appeared to spot a white vehicle entering the parking lot and moved toward it. He can be seen in the video firing at the vehicle while at least three people attempt to flee and hop the parking lot wall into a neighboring gas station. 

Later on, the assailant walked in the opposite direction toward a nearby restaurant and threw a Molotov cocktail near the restaurant's window, however the window didn't break and the device didn't ignite according to police. 

Toward the end of the video, Williams is heard firing at the officers who arrive at the scene and begin to return fire.

Police said that it wasn't until the gunfire from Williams ceased that they approached and found him dead.
