The wife of the only American killed in last week's Barcelona attack says she's trying to find a waiter who may have been 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.
Tucker grew up in Walnut Creek and was living in Lafayette.
Nunes-Tucker doesn't have a copy of the post, 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.
