SAN FRANCISCO (CBS & AP) — The wife of the Lafayette man killed in last week’s Barcelona attack says she’s trying to find a waiter who may have been be the last person to see her husband alive.

Heidi Nunes-Tucker said Tuesday that a photo or video posted on social media shortly after the attack shows the waiter trying to help her gravely injured husband, 42-year-old Jared Tucker.

Jared’s father — Dan — told KPIX 5 that as the family watched video reports on TV they spotted his fallen son and also a Good Samaritan giving him aid.

“He (Jared) had some blood on the side of his head and on his arm, but there was a person kneeing with him so we were encouraged to think it was an injury and not anything serious. But he wasn’t moving,” Dan Tucker said.

Nunes-Tucker said she doesn’t have a copy of the video but says she and her family want to find and thank the waiter.

She says anyone who stopped to help amid the chaos “is a testament to the helpfulness and love” that strangers can show for each other.

Nunes-Tucker is still in Barcelona with her family as her husband’s body was being prepared for her to take home to the Bay Area.
