WICHITA, Kan. (AP) — A Wichita man has pleaded guilty to charges in an armed robbery that led to the elderly victim’s death from stress.

KAKE-TV reports  27-year-old David L. White pleaded guilty Thursday in Sedgwick County court to voluntary manslaughter and aggravated robbery. His plea agreement allows prosecutors to request a sentence of more than 29 years in prison.

White admitted robbing 73-year-old Byron Shipman at gunpoint of his wallet and two rings in March 2013. Shipman told his wife several hours later he was upset and frightened. He then died of what a medical examiner concluded was an aneurysm caused by the stress of the robbery.

White was captured after another person he robbed the same day gave police a partial number of his license plate.
