The pregnant teen daughter of a United Airlines flight attendant found dead in the trunk of a car in Gary, Indiana, earlier this month has been implicated in her slaying.
Alyssa Barrett, 17, faces charges of murder and robbery resulting in bodily injury in connection with the death of her mother, 54-year-old DeCarol Deloney-Cain.
Barrett's boyfriend, 18-year-old Damarius Wren, was charged with first-degree murder in the case earlier this month.
According to court documents, the killing took place at the victim's Crown Point home on July 3 with Barrett present in the home when Wren attacked her mother.
Wren is accused of placing a pillow case over Deloney-Cain's head and repeatedly smashing her head against a staircase in the basement before stabbing her to death.
According to the Post-Tribune, the mother and daughter had a "fragile" relationship which got worse after Barrett became pregnant earlier this summer.
Both suspects are being held without bail.
