Police say DNA found at eight crime scenes matches DNA secretly taken from Sanchez before his arrest. DNA from Sanchez was obtained after police who were members of the Bike Path Task Force acquired it. They acquired silverware, a glass, and a napkin that Sanchez used while at dinner at a Latin American restaurant, Solé, in Amherst, New York, on January 13, 2007.
On January 15, 2007, a police task force in Erie County, New York, arrested Sanchez and charged him with the murders of Yalem, Mazur and Diver. On January 19, 2007, an Erie County grand jury voted to indict Sanchez for the murders of Yalem and Mazur.
On May 17, 2007, Sanchez pleaded guilty to the murders of Yalem, Mazur, and Diver in a surprise confession. Sanchez mumbled his confessions in court through tears. In court, Sanchez was represented by Attorney Andrew C. LoTempio, who denied Sanchez's guilt regarding all of the rapes and murders for which he was responsible. LoTempio later said that Sanchez had a troubled childhood, observed and/or had a traumatic life experience when he was 12 years old, and had deep-seated resentment toward women. LoTempio also said, however, that he was not making excuses for Sanchez.
On August 15, 2007, Sanchez was sentenced to 75 years to life in prison. He was sentenced by New York State Supreme Court Justice Christopher J. Burns. Sanchez is currently imprisoned at the Clinton Correctional Facility in the Adirondack Mountains of New York State. It has been said that he may be moved to a facility closer to his family if he confesses to further murders.
In March 2007, Anthony Capozzi was freed from state prison after serving 22 years for two rapes with a similar modus operandi. After the arrest of Sanchez, investigators realized that the crimes were similar and took place in the same area, and that Sanchez and Capozzi closely resembled each other at the time the crimes were committed. A sample of DNA from Sanchez had been linked to the rapes for which Capozzi had been wrongly convicted in 1985. Once police made the realization of Capozzi's innocence, they inquired with the Erie County Medical Center (ECMC) to obtain his DNA sample. ECMC stated that there was no DNA sample of Capozzi's on record. This was correct information. It was the DA's Office that incorrectly issued a subpoena for Capozzi's DNA, when the subpoena should have requested the victims’ DNA. Medical records and laboratory specimens are maintained under a patient's name (victims, not the alleged perpetrator(s), are the patients). Once the DA's subpoena error was realized, a new subpoena was correctly issued and the victims’ DNA samples were located, leading to Capozzi's exoneration. Capozzi maintained his innocence while in prison, and was repeatedly denied parole for over two decades. Capozzi, who is schizophrenic, and his attorney, settled a civil lawsuit for $4.25 million for being wrongfully convicted and imprisoned. Former New York State Assembly Member Sam Hoyt and New York State Senator Dale Volker introduced legislation that would expedite such lawsuits. This bill is known as Anthony's Law.
