As California police are working to identify the killer of her husband — a U.S. Marine who dreamed of becoming a drill sergeant — Alexia Truax held her baby boy and said she doesn't know how she'll ever explain to him that his father is dead.
Marine Sgt. Christopher Truax, 21, was found shot dead early Friday morning in the San Diego suburb of Lemon Grove after sheriff's deputies discovered him lying in the middle of the road, next to a car with a woman at the wheel, according to the San Diego County Sheriff's Office.
"Please help find them and figure out why they did that to him," a tearful Alexia told ABC affiliate station KGTV in San Diego.
Truax was found shot just after 12 a.m. on Friday, and was pronounced dead after deputies and firefighters tried in vain to save his life, the sheriff's office said in a statement.
No arrests have been made and homicide investigators were attempting to identify Truax's killer on Tuesday.
Investigators questioned the woman found at the scene. She was in the driver's seat of a blue Chrysler 200, but she is not a suspect in Traux's slaying, according to sheriff's officials.
Sheriff's officials would not disclose the relationship between the woman and Truax.
Alexia Truax said she did not know the woman who was with her husband when he was found shot by deputies.

She said her husband was taking classes at Marine Corp Station Miramar, near San Diago, and that his dream was to become a Marine drill instructor.
