Testimony by medical personnel dominated the third day of the Chaz Higgs murder trial, accused of killing his wife, former Nevada Controller Kathy Augustine, with a lethal dose of a paralytic drug.
A paramedic and a nurse told jurors that the 42-year-old Higgs seemed calm and unnerved as they worked to save Augustine, both at her home and in the emergency room last summer.
In other developments, defense lawyers said a cardiologist diagnosed Augustine with a heart condition in 1995, and a nurse at the former Washoe Medical Center, under questioning by Higgs' lawyer, confirmed that 22 employees were fired and one committed suicide following an internal probe after Augustine's death.
Authorities allege that Higgs, a critical care nurse, injected her with succinylcholine, a powerful muscle relaxant normally used to immobilize a person while inserting a breathing tube.
If convicted, he faces up to life in prison without chance of parole.
