Investigators are waiting on the results of a paternity test on the alleged victim's child.
Police say Mayra Gonzalez, 32, had sex with the boy six times between July 1 and Dec. 24, 2011. Most of the incidents apparently happened at the boy's home when his parents were away. Police said a suspicious neighbor confronted the boy, who then admitted the alleged relationship.
The victim is a close friend of one of Gonzalez's relatives.
Gonzalez was held on $20,000 bail while waiting for arraignment. If convicted she would be required to register as a sex offender.
