A Newnan teenager is facing murder charges after allegedly stabbing and killing her mother Thursday night during an argument inside their Coweta County home.

Tatiana Van Linden, 19, is accused of stabbing Leslie Van Linden with a kitchen steak knife, Coweta County deputies confirmed.

According to a sheriff’s office incident report, Tatiana Van Linden called 911 about 7:30 p.m. and told dispatchers that she stabbed her mother at their Edgeworth Road home. Moments later, authorities received a second call from the woman’s husband saying his wife had been stabbed and needed medical attention, police said.

Deputies arrived to find Leslie Van Linden, 54, lying in a pool of blood on the floor of the master bedroom, according to the report. She had apparently been stabbed in the chest after a dispute with her daughter. The woman was taken to a nearby hospital, where she died.

Authorities interviewed Tatiana Van Linden, who reportedly admitted stabbing her mother, saying she was sorry and that it was an accident.

Just before the stabbing, the teen had been arguing with her mother about going to the Riverwoods Behavioral Health System, a mental health facility in Clayton County, she told deputies.

Her father, who was eating dinner in the living room at the time, told investigators he could hear the two arguing about whether Tatiana Van Linden had been taking her medications before his wife screamed.

According to the police report, Tatiana was not the Van Lindens’ biological daughter. The couple adopted her years earlier after the state of Florida took custody of the girl from Leslie Van Linden’s brother.

Tatiana Van Linden was arrested at the scene and charged with murder. She remains held without bond in the Coweta County Jail, records show.
