A St. Louis County woman facing criminal charges for injuring her sons by lighting fireworks inside an SUV has been found dead.
The St. Louis Post-Dispatch reports that 44-year-old Kara Koriath was found Tuesday morning by a relative with a single, fatal, gunshot wound. Investigators found after-death instructions inside Koriath's home, along with a will, suicide letters and a recently-purchased life insurance policy.
Police say Koriath intentionally lit strategically-placed fireworks while driving along Interstate 270 in November, causing the SUV to catch fire and crash. Her sons, ages 13 and 16, suffered burns and smoke inhalation.
Authorities suspect her motive was to seek revenge on her married lover, who was expected to be driving along the same route. She was free on $200,000 bond.
