CORPUS CHRISTI, Texas (AP) Authorities believe an 86-year-old retired neurosurgeon fatally shot his wife before killing himself.

Police Lt. Isaac Valencia tells the Corpus Christi Caller-Times that Dr. Joseph Klotz and 83-year-old Carol Klotz died Monday at their home after being shot in the head.

Emergency medical services were dispatched after receiving a report of a fallen elderly person. At the same time, the residents called a home care provider.

The home care provider had been assisting Carol Klotz when Joseph Klotz asked her to wait in the kitchen. Police say that while waiting, she heard a gunshot and looked in the bedroom to see the man pointing a handgun at his wife.

The home health care provider ran outside to call 911 and heard another shot.
