One Franklin County man is in the hospital and another is in custody following an altercation Monday night that ended in a stabbing, authorities said.

Franklin County Sheriff Gary Toelke said his officers are investigating the incident in which 35-year-old Nathaniel Rankins, Gray Summit, was wounded.

The sheriff reported that Rankins sustained stab wounds to the abdomen and leg. He was taken by ambulance to Mercy Hospital St. Louis, Creve Coeur, for treatment.

The incident happened about 11 p.m. at a home on Hammer Drive.

Toelke said deputies on the scene were told that Rankins and his wife were involved in an argument and when the wife tried to leave, Rankins attempted to disable her vehicle.

The wife told deputies that her mother’s boyfriend arrived at the residence with a large knife. An argument ensued during which Rankins was stabbed, according to the sheriff’s office report.

The suspect, age 60, was taken into custody at his home, also on Hammer Drive, where deputies seized a hunting knife and other knives as evidence, Toelke said.

The suspect’s name was not released because he has not been charged.

Toelke said Tuesday that the victim’s condition was not known.
