Investigators then tracked down a man and woman who had made that call from a payphone. They're believed to be residents of the home where the shootings happened.
"It does not appear to be a home invasion at this time," said Sgt. Bryan Pair with the Harris County Sheriff's Office. "Apparently, they met here. They somehow know the individuals involved, but to what extent we don't know at this time."
Those residents were taken in for questioning.
