Authorities in Chile say that a yoga instructor originally from Texas shot and killed two men who invaded her home on the outskirts of Santiago.

The men broke into the bedroom of 61-year-old Hari Nam Kaur Khalsa, hit her in the head with a weapon and tried to tie her up on Thursday.

Prosecutor Osvaldo Soto says she broke loose, grabbed her own, registered gun from under her pillow and shot them dead. Two other men escaped.

Soto said Friday the instructor is free because she acted in legitimate self-defense.

A profile on the yoga academy website says the instructor was born in Texas and has been living in Chile since 1979.

She told local Radio Cooperativa that she prefers not to talk about the incident now.
