"My beloved and cherished son, Nathaniel Marston, who was putting up the good fight until last night, was not able to continue due to the traumatic and devastating nature of his injuries," she wrote Wednesday. "Nathaniel passed away peacefully as I held him in my arms."
According to the Huffington Post, police said Marston likely fell asleep while driving on Oct. 30, causing him to lose control of his pickup truck. The vehicle reportedly flipped before Marston was ejected, breaking parts of his back and neck.
Marston was known for his role as Michael McBain in "One Life to Live." He also appeared in "As the World Turns."
