 She lived in Eagle Pass, Texas, and on April 20, 2017, the couple married and moved to California. "I don't know how to tell him or explain to him that his father isn't here," Alexia Truax, told KGTV of her year-old son, Chris. The 20-year-old was living in their Eagle Pass, Texas home with their 11-month-old son while Truax was stationed at Marine Corps Air Station Miramar — about 15 miles from Lemon Grove. Inside, they found Sgt. Truax, who was raised in the upstate New York town of Horseheads, joined the Marines after graduating from Horseheads High School in 2014. He was assigned to the Marine Wing Support Squadron 373s as a food service specialist, Lt. Col. James Bauch, commander of the squadron, said in a statement. "We join Sergeant Christopher Truax's family in mourning the loss of a loved one," Lt. Col. James Bauch, commanding officer of MWSS 373, said in a statement. "He was a valued brother-in-arms to all who served with him, and will be missed. We wish them comfort as they navigate the difficult days ahead."
– Alexia Truax married her best friend last spring before giving birth to the couple's son in September. A year later, her world has been turned upside down. "Speechless" is how the 20-year-old Texas resident describes feeling after learning her husband, Marine Corps Sgt. Christopher Truax Jr., was fatally shot in the head in California early Friday, per Fox News. A native of Horseheads, NY, and a food service specialist with the Marine Wing Support Squadron 373 based out of Marine Corps Air Station in Miramar, the 21-year-old was found with a gunshot wound to the head in a car parked in the middle of a street in the San Diego suburb of Lemon Grove just after midnight Friday and pronounced dead half an hour later, reports KFMB. No bullet holes or shell casings were found in the car, per NBC San Diego. Offering a $1,000 reward for information leading to an arrest, the San Diego County Sheriff's Department has released little other information except to note that a woman in the driver's seat of the blue Chrysler 200 is considered a witness to the homicide; her relationship to the victim wasn't disclosed. Truax says she doesn't know the woman, per ABC News. She adds her husband, who joined the Marine Corps in 2014 and was later deployed, had been taking classes at the station 15 miles from Lemon Grove and dreamed of becoming a drill instructor. "It kills me to know I will never be able to hear [his] voice again," she tells Fox. Of her son, she adds to KGTV, "I don't know how to tell him … that his father isn't here."
