The ex-boyfriend of a woman from New Jersey who has been missing for almost three weeks sent her several angry, profanity-laden text messages the night before she vanished.

John Ozbilgen, 29, sent at least 10 texts and Facebook messages to his ex, Stephanie Parze, on October 30th according to prosecutors.

He told her that 'she always has to make their relationship suck' and called her a 'f***ing c***,' Monmouth County Assistant Prosecutor Caitlin Sidley said.

Things had become so bad between the pair that Parze, 25, had filed a simple assault domestic violence complaint against Ozbilgen in September, according to the Asbury Park Press.

While investigating Parze's disappearance, detectives noticed marks around Ozbilgen's neck.

Ozbilgen has been named as a 'person of interest' in his ex-girlfriend's disappearance but has not been charged in the case.

Ozbilgen has been in jail for the past 11 days on unrelated child pornography charges but was released on bail on Tuesday.

Ozbilgen was arrested after authorities said they conducted a 'forensic review' of his home and iPhone X whereupon 'an image of child pornography was found'.

Investigators are said to have found at least nine images of children as young as three being sexually abused according to NJ.com.

Ozbilgen has been charged with child porn possession and if convicted faces up to five years in prison.

'Ozbilgen's violence against women is borne out in his history, as well as pornography he seeks out of very young children. There are no conditions that can keep this community safe,' Monmouth County Assistant Prosecutor Caitlin Sidley said.

While the search of the stockbroker's Freehold Township home was related to Parze's disappearance, his detainment was 'completely unrelated', police said.

Monmouth County Prosecutor Chris Swendenman said two electronic devices were seized but would not clarify whether they were seized in relation to missing Parze.

According to her Facebook profile she was in a relationship with him from August 19 but at the time of her vanishing she was single.

Parze vanished from her home in Freehold Township at around 10pm on October 30, according to the Monmouth County Prosecutor's Office.

Parze's parents said their daughter and other relatives went to see a medium for a séance in New Brunswick that evening, after which they returned to the family's home.

Parze then headed to her late grandmother's house, here she had been staying, reported Asbury Park Press. The next morning, she failed to show up at work, prompting her parents and sisters to go to the authorities.

Her family last saw her in a Snapchat video driving home but said she was likely with the man she had been seeing

Police found Parze's car parked in the driveway and her cellphone inside the house.

She vanished from her home and had the lights left on. There was no sign of forced entry or a struggle. Her dog had been left alone inside.

'She would never go out of the house without her phone,' said Sharlene Parze. 'And she was supposed to be at work and she never showed up. Everything is just not her. You know, and I had just left her. And she was supposed to text me when she got home and she never did, but we know that she made it home because her car was in the driveway.'

Her parents told News 12 New Jersey Parze was likely with a man she had been seeing on and off.

His house was searched in relation to missing Parze but cops found child porn on his phone. Authorities said they conducted a 'forensic review' of the iPhone X

Ozbilgen was charged with possession of child porn and jailed for 11 days until he was released on bail earlier this week

The missing woman's father, Edward Parze, said the last time he saw Stephanie was in a Snapchat video that showed her driving home after the family's séance outing.

'We just want to find her,' he said. 'She's not the type of person who wouldn't text, 'Hey mom, I'm on my way to work.'

Edward Parze described Stephanie, the eldest of four daughters, as tough and independent, but also caring.

He told NBC 4: 'Definitely not like her. If she can get to me, she would. Not knowing is the worst. All we can hope for is that she's alive and OK. The things that go through my head are horrible.'

Authorities have recently searched parts of Staten Island several times in the hopes of finding Parze but had not commented what, if anything, has been found. Ozbilgen previously lived in Staten Island.

According to her Facebook page, Parze attended a vocational school for cosmetology and worked as a makeup artist and pat-time baby sitter.

She is described as 4ft 11in tall, weighing 115lbs, with brown eyes and brown hair. She was last seen wearing jeans, a burgundy v-neck shirt and burgundy sweater.

Anyone with information on her whereabouts is being urged to contact Detective Shawn Murphy of the Monmouth County Prosecutor's Office at 732-431-7160 ext. 7032, or Detective Daniel Valentine of the Freehold Township Police at 732-462-7908.

Parze and her family members attended a psychic seance but she failed to show up to work the next day, raising alarm bells
