HARRIS COUNTY, Texas – Harris County authorities said they are investigating an apparent murder-suicide in north Harris County.

Officials said a man shot his wife to death before killing himself Wednesday around 8 p.m. at a home in the 900 block of Pear Tree Lane.

It is not clear what led up to the shootings.

Deputies said the couple's son found his parents' bodies in the backyard of the house.

Authorities said the wife's medical issues may have played a role in the shootings.

“It’s especially sad, these are two individuals who have lived in this neighborhood for decades, longtime members, lots of friends all saddened,” Jason Spencer, with the Harris County Sheriff's Office, said.

The husband and wife were the only two people home at the time of the shooting.
