A Bloomfield man has admitted raping a toddler — a guilty plea that will send him to prison for 25 years without a chance for parole.

Jaime Mauricio Leon, 34, was arrested a week after a witness told police on June 16, 2017, that he had seen a man and a woman sexually abusing a toddler when he looked through a bedroom window of a home in Long Branch.

The woman was arrested the same day that the crime was reported to police. Olga M. Diaz, 32, was charged with five counts of aggravated sexual assault and two counts each of child endangerment, permitting a child to engage in child pornography, manufacturing child pornography, possession of child pornography, intending to distribute child pornography and distributing child pornography. She also was charged with conspiracy to commit sexual assault and conspiracy to permit a child to engage in child pornography.

"The citizen provided law enforcement with evidence of a female and male suspect committing various acts of sexual acts upon a child who appeared to be asleep," Monmouth County prosecutors said Tuesday. The incidents happened June 15 and 16.

Police identified Leon as the suspect and arrested him at a Fort Lee job site on June 23, 2017.

Investigators say Leon and Diaz "had planned the attack on the child, and that both were in possession of child sexual abuse images." The child was known to Diaz. Authorities and New Jersey 101.5 do not publicly identify child victims of sexual abuse.

Leon's attorney, Michael Kuhns, declined to comment. Diaz's attorney, Carlos Diaz-Cobo could not immediately be reached for comment Tuesday.

Leon pleaded guilty Wednesday to first-degree aggravated sexual assault and third-degree possession of child pornography.

He will be sentenced in August. In addition to the mandatory sentence, he also faces parole supervision for life.
