The crime took place on the day of Thanksgiving in front of the eyes of the perpetrator's grandmother and the victim.
Police who arrived at the house where the murder took place found 23-year-old Owen Crowe with a gunshot wound to the body with the unfortunate girl leaving her last breath in the hospital where she was taken.
The grandmother of the 27-year-old perpetrator described to the police how the murder took place. According to what the 23-year-old told them, she was sitting in a chair with her 1-year-old child in her arms when the 27-year-old appeared, who was upset by his sister's decision to block him on Facebook.
The elderly woman also said that suddenly the 27-year-old pulled out a gun, marked his sister and shot.
The 27-year-old reportedly told his grandmother not to call the police after the shooting because he did not want to shoot.
The same version was claimed by the perpetrator and to the police that he accidentally shot the 23-year-old with a Glock which "turned on his fingers when it fired".
The 27-year-old remains in custody as a judge set $ 500.000 bail.
