Police said a gunman drove up to a man and woman outside the federal agency’s Orlando Field Office on Corporate Centre Boulevard near Lee Vista Blvd and South Goldenrod Road at about 10:15 a.m.

They said the gunman shot the man to death, and the woman was able to escape.

Investigators said an officer spotted the gunman’s vehicle, and the suspect led police on a chase to a home near Kissimmee -- about 15 miles away. That is where he was arrested.

Orland Police have confirmed that the shooting was domestic in nature. According to police, the man who killed was with a female companion who was not hurt. The suspect was her ex-husband, police said.

Police said they have identified the suspect as Alberto Rivero-Milian, 52. He remains in custody in Osceola County Jail.

The victim has also been identified as 52-year-old Alberto Dominguez-Ortiz, police said.

Investigators said he had driven up to Orlando from South Florida with Rivero-Milian’s ex-wife.

Immigration attorney Rusten Hurd told Channel 9 that people in the building ran away from windows and doors in a panic after hearing the gunfire because they were scared someone was attacking the office.

“There was a desk inside the immigration officer’s office, and we all got down behind it -- probably 20 of us in a small office,” Hurd said. “It was really helpful for him to do that.”

The office will be closed Tuesday and will reopen Wednesday. Any missed appointments will be rescheduled.
