An Oregon family has filed a $100 million lawsuit alleging that 18-year-old Ethan Cantrell died from a severe infection after doctors at Good Samaritan Regional Medical Center failed to properly clean debris from a puncture wound in his arm before stitching it closed.

The lawsuit claims that wood, pine needles, and other organic material were left inside the wound, leading to a rapidly worsening infection after he was discharged with antibiotics.

When Cantrell returned to the hospital with increasing pain, swelling, and fever, doctors later discovered multiple foreign materials and a bacterial infection after reopening the wound.

He was transferred to a larger hospital, where his condition was recognized as life-threatening and his arm was amputated, but he later died from necrotizing soft tissue infection, NBC News has reported.

The family alleges medical negligence by the hospital and physicians, while the hospital says it will respond through the legal process.
