Bethlehem Police filed additional charges against a 20-year-old man they say is a serial rapist.
David Martinez was arrested earlier this month in connection with the rapes of two teenage girls he met on Facebook, police say six women have stepped forward since.
The charges presented Wednesday are related to three women, two of whom court records show were 17-years-old and pregnant at the time of the attack.
Martinez is set to be arraigned on the third new charge Thursday morning.
So far, investigators say the modus operandi in each of the cases has been very similar.
"There's a pattern and that pattern is using Facebook as a method of contact and then meeting these girls and bringing them back to his home essentially," said Northampton County District Attorney John Morganelli.
One of the latest victims told police she was attacked twice by Martinez.
Court records say Martinez friended her on Facebook in April 2011 and sent her comments on her photographs stating she was "pretty".
The alleged victim later met Martinez at a McDonald's on the South Side of Bethlehem, where he drove her to his home on Maple Street and parked close by.
While in the car, she said Martinez pinned her down and attempted to kiss her.
After a brief confrontation, Martinez climbed off and she got out of the vehicle.
The alleged victim stated to police she did not hear from Martinez again until December 2011, at this time she was 7 months pregnant and said Martinez was aware of her pregnancy and had sent her a message stating "I miss you".
During a visit at his house she said Martinez again pinned her down and tried to rape her, after approximately 15 minutes of fighting she left the home and said Martinez sent her a text message stating "never contact me again".
Court records show the other victim was 4 months pregnant at the time of her alleged attack which took place in June 2012.
She told police Martinez drove her to Lookout Drive on Lehigh University's campus and raped her inside his vehicle.
After the attack, the alleged victim says he dropped her off at her home and sent her a text message stating "I am sorry again please forgive me. I don't want you to hate me. Can you please keep this between us because that was really definitely not me. I am sorry."
"I do believe he is a serial predator, a sexual predator based on his own admissions that he indicates that whenever he's in the presence of females and he seeks them out on the internet, he wants to have sex with them this is someone who essentially cannot control his urges," said Morganelli.
Morganelli added Martinez may face additional charges, "We have about three more that are possibilities here so we're up to eight right now and we're hoping that's the end of it but the investigation is continuing."
Any other potential victims are asked to contact the Bethlehem Police Department at 610-997-7674.
