Two victims of South St. Paul fire identified

The Hennepin County Medical Examiner Thursday identified two of the three fire victims who died in a South St. Paul house fire earlier this week.

Soeun Sem, 60, and his 20-month-old son Eric, died of fire-related injuries at the home, according to the medical examiner.

The third victim died at Regions Hospital in St. Paul. The Ramsey County Medical Examiner's office declined to release his identity or cause of death Thursday.

South St. Paul fire investigators have not determined the cause of the fire. The boys' mother was at work when the fire broke out Tuesday evening.
