Four people are expected to make an initial appearance Tuesday in Adams County Circuit Court in connection with the disappearance and overdose death of a 33-year-old man.

Isaac Salinas was reported missing Sept. 11. His body was discovered one week later beneath a pile of wood near a shed.

Charges were filed in October against 55-year-old Debra Phillips of Friendship; 46-year-old Michael Mathewson of Adams; 51-year-old Jacquet Jenkins and 46-year-old Susan Hall, both of Oxford.

Phillips faces charges of first degree reckless homicide by delivery of drugs and hiding a corpse. She is being held in the Adams County Jail on a $30,000 cash bond.

Jenkins faces charges of first degree reckless homicide, possession of narcotic drugs, possession of drug paraphernalia, and second offense possession of marijuana. His bond is also $30,000 cash.

Mathewson and Hall both face charges of hiding a corpse and obstruction. A judge set bond for Mathewson at $50,000 cash, while Hall is being held on a $5,000 bond.

All four have been in custody since late September.

Court documents allege Phillips purchased heroin from Jenkins and provided it to Mathewson, Hall and Salinas. Salinas reportedly became unresponsive, but Mathewson dismissed concerns about his Salinas’ well being, saying Salinas had “done that before.” Mathewson said he continued to check on Salinas, who later died.

Phillips and Mathewson allegedly removed the body from Hall’s bedroom, according to court documents. Police say the two intended to put Salinas’ body in a lake, but placed it near a shed on the property when the body became too heavy to move.

The pair allegedly covered the body with a large sheet of plywood before returning to the home to use more heroin.
