Horn has not been arrested or charged with any crime. The grand jury just began hearing evidence in this case Monday.
The medical examiner's office ruled the deaths of Diego Ortiz and Hernando Torres homicides. The two men died after being hit when Horn allegedly fired his 12-gauge shotgun at them.
Horn's attorney, Tom Lambright, tells Eyewitness News that Horn would likely testify about the shootings if invited by the grand jury. He says there's a "good possibility" that Horn might testify.
"They expect him to come down there to say 'I didn't mean to do this. I was trying to do my public duty. I really just told the police what was going on and I intended to go back into my house and forget about it'," said KTRK legal analyst Joel Androphy. "They know what to expect from him so that may be the reason they're not asking for it. But I anticipate by the end of day, they will."
Lambright says, though, that neither he nor his client have received any such invitation to testify before the grand jury. He says Horn did what he thought he had to do at the time, that he regrets what happened.
Scott Durfee, that spokesperson for the DA's office, says the grand jury will continue its review of the facts next week.
