The Iowa State Penitentiary in Fort Madison remains under lockdown status after an incident that sent one inmate to the hospital with serious injuries last Friday morning. State Pen spokesperson Rebecca Bowker identifies the two inmates involved in the incident as 44-year-old David Lenox and 23-year-old Christopher Langley.

“Mr. Langley was severely injured,” Bowker said. “He was transported to the Fort Madison Community Hospital and then University Hospitals in Iowa City. He has since been returned to the prison and is in our health care unit.”

Both Langley and Lenox are serving life sentences for first-degree murder. Bowker says the altercation between the two men remains under review, but it appears Langley was stabbed in the neck.

“He did obtain severe injuries that did involved a knife,” Bowker said. Lenox was not injured. He started serving a life sentence in November of 2000 after pleading guilty to the murder of 35-year-old Ruth Melver of rural Grundy County.

Langley was one of three teenagers convicted in Scott County in the 2004 murder of 53-year-old Mark Willis – a janitor from Davenport. No prison guards were injured in last Friday’s incident.
