CONROE, Texas -

Montgomery County sheriff deputies are investigating what led to an apparent murder-suicide in Conroe.

Investigators said Donald Jacobson, 69, called his son-in-law Wednesday night just after 11 p.m. and told him he had killed his wife, 65-year-old Lucille Jacobson.

When deputies arrived at Thousand Trails RV Park in the 11700 block of Thousand Trails, they found the woman had been shot to death.

Officials say they also found Donald Jacobson had turned the gun on himself and taken his own life.

Two small dogs who were also found on the scene were picked up by Animal Control and later turned over to the couple's daughter.
