The Marine Corps has an old phrase, Semper Fidelis. It means “always faithful.” This attitude of service certainly rang true this weekend, when 61-year-old veteran Donnie Navidad instinctively dashed forward to catch a woman on a 50 foot free fall inside the Oakland Raiders’ stadium.

“He simply saved her life,” Alameda County sheriff’s Sgt. J.D. Nelson stated.

Navidad grabbed and embraced the plummeting stranger and the two slammed into the concrete together. The softened impact still left the woman hospitalized in critical condition. Paramedics cut off Navidad’s “Bo” Jackson jersey to access his wounded arm.
