A burglar had a shock attack when he broke into the home of 67-year-old Lorenza Marrujo – and discovered she was a black belt with more than 2 decades of martial arts training.

According to an interview Marrujo conducted with CBS Los Angeles, the intruder first broke into her apartment. And as he was approaching her, she calmly and confidently told him to “back off.” Realizing that, despite her 5ft tall petite frame, she wouldn’t be an easy target, the intruder left.

But unfortunately, he didn’t leave the apartment complex entirely. Instead, he made his way to the neighbor’s apartment, 81-year-old Elizabeth McCray.

“He grabbed me and shook me, and I went down on the floor,” McCray said in the interview.

Hearing the cries for help, Marrujo dialed 911 and ran to her neighbor’s aid.

She quickly positioned herself between McCray and the intruder before jumping on him and punching him.

“I squeezed myself between her and him. I put mama on the side, and I jumped on him, and I was punching him and everything,” Marrujo said. “And I had the cane against his throat.”

“He lifted up and tried to twist my hand. At the same time, I twisted his and turned it around real fast,” Marrujo continued. “And he was saying, ‘you’re hurting me, you’re hurting me.’ And I said, ‘I don’t care. I don’t care what happens to you. You had no right to hurt an elderly person.'”

She admitted that she didn’t plan to kill him, but just detain him until authorities could arrive.

McCray was in disbelief of her neighbor’s bravery and said to be careful and “he’s going to kill us both.” But Marrujo wasn’t worried. “Not tonight,” she replied.

Marrujo held the intruder captive until police arrived and took him into custody.
