His father knew something was wrong, Otero said, citing several instances in the days before the murders that were "very suspicious." One time when the power went out, his father made the family get into a closet until he made sure the neighborhood was also dark.

Another time, when a telephone repairman showed up at the house, Joseph Otero made his son go to a window to make sure there was a company van there before he opened the door.
Just days before he was killed, Joseph Otero, who worked as an aircraft mechanic, tried to give his son his ring in case something happened to him.
"Nobody hated my family," Otero said. "I am sure it had something to do with my father's military history. My dad did things. … He had to tell somebody what he had been up to in the last few years and he was dead days later."
Otero said an overheard telephone conversation his father had days before his death is the reason for his belief in a military connection. He said his father was involved with the Inter-American Air Forces Academy, a program that has trained Air Force personnel from Latin America for 60 years.
