Julio Hernandez Sr., 58, confronted his 16-year-old daughter and her boyfriend, Jose Pelayo-Sanchez, 20, of Petaluma, at a residence in the 1100 block of St. Anthony Way around 2:30 p.m., Sgt. Ed Crosby said.
Hernandez allegedly got a machete from his truck and threatened Pelayo-Sanchez. When his daughter intervened, Hernandez allegedly struck her on the left wrist with the machete causing a laceration.
He was arrested without incident at his home and was booked into the Sonoma County Jail for assault with a deadly weapon, criminal threats and child abuse.
Hernandez's daughter was treated for her injury at Petaluma Valley Hospital and released.
The incident happened days after 40-year-old Juan Manuel Landaverde fatally shot his 15-year-old niece Karen Flores in their Santa Rosa home then fatally shot himself with a shotgun. Santa Rosa police said Landaverde was controlling and was upset with his niece's interest in boys.
Landaverde asked Flores to speak with him privately in his room and shot her in the neck when she refused, according to police. Autopsies on both were scheduled for today.
