The father of a murdered 9-year-old girl took a polygraph test Thursday, a little more than a week after submitting DNA samples to the police.
Richard Lyons Sr., father of Mya Lyons, was escorted by Chicago police officers to a police station, according to neighbors in the 8400 block of South Gilbert Court who declined to be identified.
Lyons found Mya stabbed in the neck and stomach in a dead-end alley July 14, about a half block from the family’s South Gilbert Court home. She succumbed to her injuries a few hours later. The girl had been staying with him for the summer.
Police declined to confirm whether Lyons took a lie detector test but said the investigation is ongoing, and the family has given their full cooperation from the onset of the investigation.
Earlier this week, a knife with blood on it was found near where Lyons discovered Mya. Lab results are pending from the police department.
A “person of interest” had been questioned last week but was released.
A $6,500 reward has been offered for information leading to the arrest of the girl’s murderer.
