The Bexar County sheriff's Department is investigating an apparent murder-suicide after two bodies were found inside a home on Tuesday morning.
The bodies of a man and a woman were found inside the master bedroom of a home in the 11000 block of Buck Canyon after a co-worker of the woman went to the home to check on her welfare.
The deceased woman has been identified as Deanna Tiller, a 50-year-old music teacher at Allen Elementary School in the Northside Independent School District.
The name of the deceased man was not immediately available.
Investigators said they believe the shooting occurred Saturday night.
Tiller's 20-year-old son told investigators that he heard his mother and her boyfriend arguing on Saturday night, so he left the house and came back later.
He told deputies that he rarely interacted with the couple and did not know that there had been a shooting.
BCSO spokesman Paul Berry said the man was found on the edge of the bed with a single gunshot wound to the head. The woman was found face down inside the bathroom.
Detectives were still waiting for the medical examiner around noon to arrive and determine if the woman was shot and, if so, how many times.
Tiller had worked at Allen Elementary School for two years. She previously worked at Murnin Elementary School for four years.
