He's accused of killing 28-year-old Michael Childers after bursting into his father's home in February of last year. Childers' father, Leonard Bird, says he's looking for resolution and justice. "I'm glad for one thing - this man is arrested. I'm hoping he goes to jail forever," Bird said. Limardo is being held on $2 million bond. Police are searching for a second suspect.
