A Tennessee man was arrested in Nashville on Tuesday after stabbing to death his mother and sister-in-law, and critically injuring a second sister-in-law who shielded two young children from the "enraged" attacker, authorities said.

John Donaldson, 32, was taken into custody in a motel parking lot in West Nashville hours after the stabbings at an Elm Hill Pike apartment and a home on Hickorydale Drive, Metro Nashville Police said.

Investigators said Donaldson knocked on his mother’s apartment door around 11 a.m. and his 9-year-old nephew let him in. Donaldson entered "enraged" and attacked his mother, 56-year-old Jacqueline Pritchett, with a knife, fatally stabbing her.

Donaldson then began stabbing his sister-in-law, 29-year-old Genell Stewart-Tuggle, as she tried to shield the 9-year-old boy and Donaldson’s 7-year-old niece, police said. Stewart-Tuggle was critically injured and being treated at Vanderbilt University Medical Center. The children were unharmed.

Donaldson fatally stabbed her with a knife, according to investigators. Another 7-year-old niece was in the home at the time and unharmed.

After his arrest, Donaldson was taken to General Hospital for treatment of a hand laceration he apparently suffered during the attacks, police said. He was charged with two counts of murder and one count of attempted murder.
