GRAND JUNCTION, Colo. (AP) — The death of a Colorado jail inmate suspected of killing a 9-year-old girl with chloroform has been ruled a suicide.

Authorities said Jeffrey Beagley, 34, of Grand Junction, died after he was found unresponsive in his cell at the Mesa County jail on Dec. 23.

Mesa County Coroner Victor Yahn's investigation found that Beagley died by hanging and that jail footage did not show anyone entering his cell around that time, the Daily Sentinel reported Tuesday.

Beagley was arrested on suspicion of murder, reckless manslaughter, attempted sex assault and child abuse resulting in the death of the girl on Nov. 9. An autopsy found she died of chloroform poisoning.

Investigators say a bottle of chloroform had been delivered to Beagley a day before he called 911 to report the girl had died. Chloroform can render a victim unconscious, court documents said.

Police said they found a large amount of child pornography in the home as well as evidence of hidden cameras inside bathrooms.
