BOSTON (AP) — The father of one of the three people who died in the Boston Marathon bombings was at first told that his daughter had survived, but was in surgery and could lose a leg.

When William Campbell arrived at Massachusetts General Hospital, however, he learned that his daughter, 29-year-old Krsytle Campbell, had died.

Krystle’s grandmother, Lillian Campbell, told multiple media outlets that her granddaughter and a friend were together at the marathon and lay side by side on the ground after the bombs went off.

Somewhere on the way to the hospital, their names got mixed up.

Lillian Campbell says her son was "devastated" when he found out the truth and almost passed out.

Krsytle Campbell was a restaurant manager who grew up in Medford but had moved to Arlington.
