Pair indicted for allegedly selling fentanyl that resulted in an overdose death

Suffolk County District Attorney Raymond A. Tierney today announced the indictment of Steven Pesantez, 29, of Brentwood, and Isaiah Skees Pierre Louis aka Isaiah Skees, 27, of Bay Shore, for multiple counts of Criminal Sale of a Controlled Substance in the Third Degree and several related charges. Pesantez is accused of selling fentanyl that allegedly caused the death of a former high school acquaintance. 

“No child should ever have to find their parent dead from an overdose,” said District Attorney Tierney. “Public safety demands that we treat each of these deaths not as accidents, but as preventable tragedies caused by deliberate criminal conduct.” 

According to the investigation, on February 12, 2025, a 4-year-old discovered her father deceased in Brentwood.  The Suffolk County Medical Examiner would later rule the death was the result of fentanyl intoxication.

In their attempt to locate the source of supply of the fatal batch of fentanyl, police separately began to investigate Skees as an alleged supplier of pressed fentanyl pills in the Amityville area.  A member of the police department, acting in an undercover capacity, allegedly arranged to purchase pressed pills from Skees on three separate occasions between late February and early March 2025.  On two of the three occasions, Skees was allegedly driven to the location of the prospective exchange by a subject later determined to be Pesantez.  After the first sale of pills to the undercover officer, Skees allegedly reached out to the undercover officer in a text exchange to inquire as to how the undercover liked the product, to which the officer pretended to dislike the pills.  Skees allegedly responded by texting “I don’t get the crazy strong ones no more.  My man caught a body off them.”  That exchange came six days after the death of the Brentwood father.

On July 22, 2025, Pesantez was arrested for an unrelated burglary, for allegedly breaking and entering into the home of his former girlfriend.  At the time of the arrest, a probation search was executed at Pesantez’s home, at which time law enforcement allegedly recovered a quantity of blue M30 pills believed to be Percocet, a highly addictive opioid usually prescribed by doctors to treat pain.  The pills were identical in size, color, and markings as those allegedly sold by Skees to the undercover officer.  Also allegedly recovered were a quantity of cocaine, and a digital scale.  

On August 1, 2025, Skees was arrested and charged with the sale of the fentanyl pressed pills to undercover detectives.  Upon his arrest, Skees was allegedly found to be in possession of a quantity of fentanyl powder.
