 Tucker and his wife Heidi Nunez have been vacationing in the Spanish coastal city. While Nunez has been in contact with family in the U.S., Tucker has not been heard from. 
 
 Tucker's brother-in-law, Kalani Kalnui, told ABC News, "I was in contact with [Nunez], he had to use the restroom, they were in a kiosk [to buy trinkets] in the middle of the sidewalk in the middle of Las Ramblas. He left, and seconds later she was pushed over into the kiosk and she was disoriented trying to find him. Police evacuated ... her from the area." 
 
 Kalnui said of Nunez, "She was able to get out of the area with the friend they were staying with in Barcelona, who came and picked her up." 
 
 Nunez returned to the area to try to track down her husband to see if any of the hospitals had any information about him, Kalnui said. She also visited the Red Cross to inquire if it had information about Tucker. 
 
 It's been a heart-wrenching situation for Nunez, Kalnui said. "She's not able to find out information," he said. "[Officials] haven't posted anything as far as names who are injured or deceased." 
 
 The U.S. State Department said one American was injured in the attack, although it did not identify the individual. "We can confirm one U.S. citizen suffered minor injuries," a State Department official said. "We are monitoring the situation closely and stand ready to provide consular assistance to any affected U.S. citizens." ||||| Breaking News Emails Get breaking news alerts and special reports.

 The California man who was separated from his wife in the chaotic moments of Thursday's terrorist attack in Barcelona, Spain, was among the 13 killed at the scene, his family said Friday. 
 
 The father of 42-year-old Jared Tucker, Dan Tucker, told NBC News that Tucker's wife, Heidi Nunes, confirmed her husband's death. The Walnut Creek couple were in Europe celebrating their first wedding anniversary and had just enjoyed drinks on Barcelona's wide, largely pedestrianized tourist street of La Rambla when their relaxing vacation was shattered by sharp cries. 
 
 "Next thing I know there's screaming, yelling," Nunes, a 40-year-old teacher, earlier told NBC News. "I got pushed inside the souvenir kiosk and stayed there hiding while everybody kept running by screaming."

 Some 6,000 miles from home, they found themselves in the middle of a car-ramming attack Thursday afternoon. A driver had plowed through pedestrians, killing at least 13 people and injuring more than 100. 
 
 Secretary of State Rex Tillerson said Friday an American had been killed in the attack, but did not immediately confirm the identity. 
 
 ISIS quickly claimed responsibility for what appeared to be the latest in a spate of low-tech terror attacks across Europe. 
 
 Tucker and Nunes were on a dream romantic getaway traveling through Paris, Venice and then the Catalan city. 
 
 They were enjoying drinks on an outside patio when Nunes said she wanted to go and look at some jewelry. Tucker, a construction worker, told her he was heading to the bathroom.
– The State Department has confirmed one American was injured in the Barcelona terror attack Thursday, reports ABC News, while NBC Los Angeles reports a California woman is frantically searching for her husband; it's unclear if he might be that individual. Heidi Nunes-Tucker (her last name has also been reported as just Nunes or Nunez), 40, says she and her 42-year-old husband, Jared Tucker, were celebrating their first wedding anniversary in Barcelona when Jared left his wife to use the restroom while in the Las Ramblas district. "Within seconds after that, there was screaming and yelling and people running," Nunes-Tucker says. "I ended up on the other side of the street with a group of three people and the cops just kept pushing us away," Nunes-Tucker adds. She tells NBC News she has since seen a photograph circulating online that appears to show her husband looking "very injured." But though she's contacted hospitals, she has not yet tracked him down. The US State Department tells ABC News that "one US citizen suffered minor injuries" in Thursday's attack. That person has not been identified.
