Edith Sax death: Husband claims son killed mom to collect insurance policy

HOUSTON (KTRK) -- The death of Houston nurse Edith Sax in her backyard pool was initially deemed an accident, but authorities changed their tune earlier this year saying foul play was involved in her death. Now, Sax's husband has filed a lawsuit, saying he believes Edith Sax's son killed her in order to collect part of a $5 million insurance policy.

Dr. Steve Sax is now suing his wife's son. He filed a wrongful death lawsuit yesterday.

On Friday, April 25, 2014 the body of Edith Sax was discovered in the pool at her home in the 3600 block of Blue Bonnet. She was still dressed in work scrubs and lab coat floating face down, unconscious, and not breathing. At the time, investigators believed that Sax's death was accidental. But then they discovered Sax sustained injuries which suggested she was forced under the water.

Edith Sax's son has not responded to the lawsuit.
