Santiago’s aunt, Maria Ruiz, spoke to Telemundo about her nephew and said he lives in Naples, Florida, which is about 110 miles west from Fort Lauderdale, completely across the peninsula.

“Why did he do it? He didn’t think,” a translation of Ruiz’s interview said. “That hurt me as if he were my own child. He needs to be calm and trust God.”

Ruiz also said that Santiago had served in Iraq, which has not been confirmed, and six months after returning his father passed away.

UPDATE: 4:37 p.m. EDT -- A picture believed to be of Esteban Santiago, the alleged shooter who killed five people at Fort Lauderdale-Hollywood International Airport Friday afternoon, has started to circulate and a new report claims he posted to a forum used to download terrorist videos in 2007.

Many images flashed across social media as more information of the shooting, which also saw eight people injured and taken the hospital, but many of the images have been panned as not showing Santiago.

The site posted that it is “99%” sure that two other pictures supposedly of Santiago are not of him, and the one shown above is a 26-year-old from Alaska.

Nelson also told CNN that the alleged shooter also had a military identification. However, officials did not offer immediate confirmation of that claim. Nelson also said that when people bunch up at airports it makes for a “soft target.”

Santiago is a 26-year-old from New Jersey, a law enforcement source told Fox News. Nelson said Santiago's name was found on his military ID.

Eight other people were transported to a hospital, the Broward County Sheriff’s Office said according to CNN. The total number injured was also not immediately known.

The shooting took place early Friday afternoon at around 1 p.m. EST at the airport’s Terminal 2 baggage claim, in the 21st busiest airport in the country.

The alleged shooter reportedly ran out of ammo and then laid on the ground “spread eagle,” supposedly waiting for law enforcement to arrive, witnesses told CBS affiliate WPEC.

The shooting was first reported by former White House Press Secretary Ari Fleischer via Twitter.

The Federal Aviation Administration announced that as of 2:15 p.m. that all flights within 50 miles and bound for FLL would be allowed to land, but all other aircraft are either being delayed or diverted to other airports. All other flights scheduled to leave FLL have been grounded for now.
