A Cook County correctional worker allegedly killed himself and his estranged wife Monday in a murder-suicide in Chicago's Edgewater neighborhood.
Alexander Rojo, 50, of Plainfield, allegedly shot and killed his wife, who had recently filed for divorce, Monday afternoon, the Chicago Tribune reports.
Friends said the couple had been on shaky ground since their son committed suicide a few years ago.
Rojo joined the Cook County sheriff's department in 1998, spokesman Steve Patterson said.
