Alice Woodruff walked outside to her backyard in Waterbury, Conn. last Tuesday to find her naked neighbor allegedly raping her tied up pit bull.

"I thought my dog had killed somebody because I saw a man underneath her," Woodruff told WTNH. "I started to scream. I had a citronella candle and I threw it at him, screaming 'Get off my dog, you have to get out of here.' He said, 'No, today is the day we are going to spend the rest of our lives together.'"

Woodruff told WTNH that the neighbor, whom she had never formally met before, appeared to be suffering from mental illness—he apparently explained ISIS had order him there to rape her dog.

"He pranced through the yard naked, yelling 'This is our day and you have to prosper in it,'" Woodruff told the TV station. "'ISIS sent me,' and I was thinking 'Did something like this just land in my back yard?'"

According to CBS Connecticut, Woodruff then ran inside her own, grabbed her gun, and returned back outside, showing him that she had loaded a clip.

"He kept saying this is the plan, that we were going to die today in a massacre. He didn't seem to care that I had the gun, and I kept it down," Woodruff said. "Then I gave him a warning and shot the gun to the right into the dirt."

But even at gunpoint, the neighbor appeared undeterred.

"No, he put his arms out and started walking toward me, telling me to kill him, but to know that as soon as I kill him that we were going to die," Woodruff told WTNH. "Honestly, the whole time I thought there was a bomb or gun and he was going to take it out and do a massacre."

Police took the neighbor, so far only identified as being 22-years-old, to the hospital for a mental health evaluation. Upon release, police intend to arrest the man for cruelty to an animal, sexual assault, and breach of peace.
