Mark is the older brother of former San Francisco Giants reliever Tyler Walker. 

"I’m sick to my stomach," Kathy Walker, the mother of Mark and Tyler, told the outlet. "It’s a terrible feeling, because you’re helpless here." 

Kathy told the San Francisco Chronicle that she last spoke to Mark on Thursday. The couple’s 16-year-old daughter, Ellie, was attending camp at Camp Waldemar and has since been found safe. 

According to the report, Tyler and his wife traveled to Texas to be with their niece.
