Thank you for being patient with me learning how to braid your hair, and I will never forget our duet singing the national anthem at Napa’s soccer game. I love you. I love you. I love you. You are gonna make one gorgeous angel. My heart and prayers are with every victim of this tragedy.

The couple has been frantically searching for their niece, Alaina Housley, who was inside the country-western bar when the gunfire erupted.
According to the reports, Alaina was one out of "a handful of girls who went to line dance" at Borderline and have not been accounted for.

According to Andrea Castillo, a Los Angeles Times reporter, Adam has been to the Los Robles Regional Medical Center to look for Alaina.
"A guard didn’t let him through, saying [the hospital] was on lockdown," Castillo wrote on Twitter "He said Alaina, a Pepperdine freshman, was at the bar with several friends. Her Apple Watch and iPhone still showed her location on the dance floor."
She continued, "Housley said two of Alaina’s suite mates jumped through a broken window to escape and are at a hospital with major glass wounds. As they ran away from the bar, someone screamed 'Hey! Get the (expletive) down on the ground!' They told Housley they believe it was the gunman."
"But they kept running toward houses near Los Robles Greens golf course, where they got help from residents," she added.
