DNA sample is given by East Side man charged with killing his mother

A Buffalo man accused of fatally beating his 68-year-old mother last month in their East Side home and then hiding her body in an alcove gave authorities a DNA sample Thursday after his arraignment on an indictment charging him with second-degree murder.

But William R. Tyes’ attorney questioned the value of DNA evidence because he said that any weapon allegedly used in the beating has not been found. He added that authorities believe that Tyes used his mother’s cane to beat her.

Police also reportedly want to compare Tyes’ DNA with some bloody clothing found in a duffel bag when they arrested him on the day Lenora Tyes’ body was found.

William Tyes, 38, pleaded not guilty in front of Erie County Judge Kenneth F. Case, who ordered that he continue to be held without bail.

The indictment accuses Tyes of killing his mother between Feb. 7 and 10 in their home on Dodge Street.Police searched the home on the afternoon of Feb. 10 and found Lenora Tyes’ body, after family members became concerned because she had not been seen for several days.

An autopsy determined that she died from blunt-force trauma.

Detectives located William Tyes that night at a house in the Kensington-Grider neighborhood. Hours later, he was charged with murder. A neighbor said that Lenora Tyes had kicked her son out of the house six days before her body was found and that the mother told her Tyes had stolen money from her for crack cocaine.

New York State Sex Offense Registry records list William Tyes as a Level 2 offender who in 1996 was convicted of second-degree sexual abuse involving a 6-year-old girl. He was sentenced to three years’ probation.

Joseph J. Terranova, attorney for William Tyes, said he will request a pretrial hearing on a 2-hour videotaped interview that his client gave to police after he was picked up. Terranova said the hearing will determine whether his client’s statements were given voluntarily and whether they can be used as evidence against him. He acknowledged that the defendant and his mother often argued and said that he is exploring any mental health issues that his client might have.
