Edwin Gimenez and 15-year-old Angel Rosa were ordered to remain jailed Friday after their attorneys entered not guilty pleas in connection with the murder and dismemberment of Rosa's mother.
During separate arraignments, Gimenez, 50, and Rosa were each charged with second-degree murder and criminal conspiracy in the Aug. 18 death of Madeline Irene.
Gimenez, who has a pedophile conviction from Suffolk County in the mid-1990s, also was indicted on a first-degree kidnapping charge and eight counts of a criminal sexual act in the first degree.
During the arraignments before Senior Erie County Judge Michael L. D'Amico, prosecutor Christopher J. Belling said authorities have a five-page written confession in which Angel Rosa admitted killing and dismembering his mother at Gimenez' urging.
Belling said prosecutors will be contacting their counterparts in San Bernardino, Calif., to get more information about a child-molestation arrest warrant that has been pending against Gimenez there since 1992.
After the arraignments, Robert J. Cutting, Rosa's court-assigned attorney, questioned the legality of his client's alleged confession.
Rosa was returned to the Erie County Youth Detention Center on East Ferry Street, where the juvenile offender being prosecuted as an adult is being held. Gimenez was taken back to the Erie County Holding Center.
If convicted, Gimenez faces a maximum prison term of 50 years to life. Rosa, as a juvenile offender, faces a maximum term of nine years to life.
The murder and sex cases were assigned to State Supreme Court Justice Joseph S. Forma.
Cutting and Joseph J. Terranova, Gimenez' court-assigned attorney, said they expect to seek separate trials.
Erie County District Attorney Frank J. Clark and Belling declined to comment after the arraignments.
Cutting said he will seek further information on prosecution claims that Gimenez "insinuated himself" into the family of the murder victim.
Terranova said his job will now consist of trying "to figure out what Gimenez didn't do." He said he is "ultimately looking at a trial" for Gimenez.
According to authorities, Irene, 46, was killed in her Fargo Avenue apartment Aug. 18 and dismembered over the next few days. Parts of her body were discovered in the Black Rock Channel near the foot of West Ferry Street on Aug. 23 and 24. Her skull was recovered from a garbage can packed with hardened concrete on Sept. 9, police said.
