SECOND UPDATE: A valley neighborhood is on edge after squatters set a house on fire and came back for more. People living near Tropicana and Swenson say they've had enough.
"(I heard) yelling and screaming for about two hours and finally there was an explosion and that was it," said next door neighbor Steve Collins.
The explosion led to massive flames, caught on camera by neighbors. Neighbors say a woman and three men are to blame. 13 Action News spoke with the alleged woman squatter. She admitted to living in the home but denied starting the fire. She told 13 Action News, her "roommates" started it.
"They've got squatters all up and down this whole neighborhood. It's like a squatters paradise here," said Wilson.
UPDATE: Squatters returned just hours later to the vacant house that caught fire on Tuesday morning and 13 Action News spoke to one of the people who are living in the house.
