A Jupiter Farms man is facing a first-degree murder charge after a shooting Tuesday night at his estranged wife’s home. The Palm Beach County Sheriff’s Office says Brian Canarelli  fired multiple rounds at the woman’s new partner following an argument outside a house on 98th Trail North. Investigators say the woman had called Canarelli to the home to pick up their son and that the man was upset that Canarelli was present. The woman and the boy were not injured. Canarelli remained in the Palm Beach County Jail late Wednesday.
