CALLOWAY COUNTY, KY (KFVS) - Prosecutors plan to seek the death penalty in the case of a man accused of killing a family of four in Calloway County in November.
Commonwealth Attorney Mark Blankenship officially submitted paperwork that his office will seek the death penalty for Pascasio Y. Pacheco Arellano.
Arellano is a relative to the family, two adults and two small children, who were found dead after a house fire on Nov. 17, 2015.
According to the Calloway County Coroner Rick Harris, the people killed in the fire include: Bulmaro Arellano, 29, Marisol Hernandez, 24, a 5-year-old boy, and an 18-month-old girl.
According to the family, the suspect is Bulmaro Arellano's nephew.
Arellano pleaded not guilty to burglary 1st degree, four counts of murder, arson 1st degree, and tampering with physical evidence.
Court documents led police to Pascasio Arellano's house in Mayfield after family members recorded a conversation with Arellano revealing his alleged involvement with the crime.
Detectives met with Pascasio Y. Pacheco Arellano on Saturday, Nov. 21. They noticed he was injured and took him to a hospital for treatment where he was admitted.
Court documents state clothes and a car floor mat covered with blood were also found inside the house.
After he was released from the hospital, police arrested him and took him to the Calloway County Jail.
The county attorney asked that no bond be set for Arellano based on the "horrifying facts" surrounding the case.
The judge denied his bond.
In a preliminary hearing December 2 in Calloway District Court, Judge Randall Hutchens found probable cause in a quadruple murder case and ordered the case bound over to a Calloway County grand jury.
Officials investigating the arson in Calloway County, Ky. say the two adult victims died from gunshot wounds.
According to Kentucky State Police, it is believed both children died from smoke inhalation; however, further testing is being conducted for verification.
Police say the investigation shows that the fire in the home was intentionally set to cover up the murders.
