Rie Sugiyama, 28, killed in a stabbing spree Tuesday on Guam, had been looking forward to her younger brother's wedding ceremony in the U.S. territory scheduled for Thursday — Valentine's Day.

"I want my daughter back," said Sugiyama's father, whose name has not been released. The man is also the son of Kazuko Uehara, 81, another of the three people who have died from the rampage.

About 20 members of the Sugiyama family were on Guam for the wedding ceremony. Before the attack, family members went out for dinner and were shopping in the Tumon tourist district when Uehara was struck by a car that had gone onto the sidewalk. When her son, Sugiyama's father, ran up to her she was already motionless.
