Warning: Some of the stories contain graphic details.

1. Sex assault suspect tied up woman, threatened to kill her, court docs say

A man who had been deported 20 times broke into a woman's home and sexually assaulted her in July. He was caught and arrested after assaulting another woman.

The suspect, Sergio Jose Martinez, had a long history of illegally entering the United States. His most recent deportation was in November of 2016. Immigration and Customs Enforcement (ICE) lodged an immigration detainer against Martinez, asking authorities to notify them before releasing Martinez to allow ICE to take him into custody. But that never happened, which sparked a fierce debate on social media.

Multnomah County leaders and Sheriff Mike Reese wrote a letter to the community saying, “The Sheriff's Office does not hold people in county jails on ICE detainers or conduct any immigration enforcement actions.”

Martinez was convicted of kidnapping, robbery and sex abuse, and was sentenced to 35 years in prison.
