When deputies arrived at the house, they found the young man with 鈥渟evere blunt force wounds to his head,鈥 knife wounds on his extremities and blood on his clothes, the court document said.
The young man told sheriff鈥檚 detectives he had been at school when his father called him to come home early, which he found strange. When he arrived at the house, Enriquez met him outside and said the young man鈥檚 mother, Sandra Enriquez, and 15-year-old sister, Isabel, were playing games inside the house and needed help to clean up, according to the return.
When the two entered the house, Enriquez grabbed a 鈥渓arge metal object鈥 and struck his son on the head before attacking him while saying, 鈥淛ust let me do what I need to do鈥 and 鈥淚鈥檓 taking your mom and sister and I need to finish this,鈥 the detective said in the court document.
The son began to fight back and the pair ended up in the kitchen, where Enriquez got a knife and began to stab and slash his son, according to the document.
Enriquez鈥檚 son was able to 鈥渨riggle away鈥 and escape to the neighbor鈥檚 house.
Deputies went to Enriquez鈥檚 home and forced entry after receiving no response. They saw signs of a struggle inside the home and blood on the floor in multiple rooms, the return said.
Deputies found two 鈥渇emale bodies鈥 covered in blood in a tub in one of the back rooms, with knife wounds and what appeared to be blunt-force trauma to their bodies, according to the detective.
Enriquez wasn鈥檛 in the house, and deputies went out the back door into a 鈥渞ural area,鈥 eventually finding a man laying face down in a small wash with his hands underneath him, according to the return.
Deputies repeatedly told Enriquez to roll over and show his hands, and eventually used a Taser on him. When he rolled over, police found a 6-inch kitchen knife underneath him.
He kept telling deputies, 鈥淛ust go ahead and kill me,鈥 the return said.
Enriquez鈥檚 son, who is expected to survive, told detectives his father had insomnia and was taking prescription medication and possibly over-the-counter medication to help him sleep. The son also said his father had recently suffered from depression, the return said.
Crime-scene technicians took dozens of blood swabs from various parts of the house, and detectives seized medication, electronics, several knives and other items from the home.
Funeral services for Sandra and Isabel Enriquez will be at 2 p.m. Saturday in the main auditorium at the Tucson Baptist Church, 1525 S. Columbus Blvd.
