AN American man captured in Cambodia in March and sent back to the United States to face charges in connection with the stabbing death of his mother has been sentenced to 10 years to life in prison, US media reported this week. Nathan Helburn, 34, reportedly stabbed his 61-year-old mother 17 times on or around March 5 before fleeing to Cambodia. The Associated Press reported that the victim Mary Helburn was discovered on her kitchen floor on March 9 “with stab wounds to her head, back and neck”. Nathan Helburn was captured on March 18 and returned to the US state of Idaho five days later, where he pleaded guilty to second-degree murder.
