It was nearly 2 a.m. in September 2009 and Sgt. Mark Conway was wrapping up an off-duty patrol job he had worked for the past five years.

The Seminole County sheriff's deputy said he was just four or five minutes from leaving the Oviedo apartment complex when someone suspicious showed up.

Patrick Macchione was dressed in black and was carrying a backpack, and when he saw Conway in the unmarked car he tried to go the other way.

Conway said he had never seen Macchione before, so he knew he didn't live there and figured him for a car burglar.

He stopped him and asked to see inside his backpack.  Macchione began acting apprehensive and didn't want the deputy looking through his possessions.

"I thought he was a car burglar, and expected to find car stereos or GPS units inside," recalled Conway.

Instead, he found a video camera and dozens of videos of Macchione addressing someone named "Kristin."

"I have no doubt if he would have encountered her he would have hurt her or killed her," said Conway.

He booked Macchione on a loitering and prowling charge and plugged his name into a department database.  He found police reports and injunctions against Macchione from Kristin Pratt.

Pratt, now 23, was a UCF student at the time who knew all too well what the videos Conway found in the backpack contained.

When Conway called her and said Macchioned was in custody, Pratt said she sighed a breath of relief.

"I've been trying to tell people this for years now and no one wants to listen to me," she said, "Sgt. Conway saved my life."

Pratt barely knew Macchione.  They had a dual enrollment college credit class together when they were both still in high school in 2007.  Pratt was from New Port Richey, and Macchione was from near Gainesville.

"I didn't even know he existed in that class," said Pratt.

But he remembered her.

About a year later, in January 2008 he started messaging her on Facebook.  He mentioned the class and she responded in a friendly manner.

"Just, 'Hi, how are you, how have you been?'" she said.  "I was never flirtatious."

Within the first five or six messages, Pratt said Macchione's tone changed from friendly to strange.

She said countless phone calls, text messages, emails, Twitter and Facebook messages started showing up.

He called more than 40 times one evening while she was at work, and she called police.

"I called the police and they came and said, 'Well, he doesn't know where you live, does he?'  And I said, 'No', and he said, 'Well, there's nothing we can do,' and they just left," recalled Pratt.

Then he started posting videos on Youtube. Some are friendly, where he is asking to take her on a date.  In others, he is angry and threatening his own life and hers.

In one, he is masturbating and asking Pratt to be with him. In June 2009, she filed a petition for an injunction in Orange County and handed in over 200 pages of information detailing the harassment. 

Later that month, an Orange County judge awarded Pratt a 10-year injunction that forbade Macchione from being within 500 feet of her place of employement at any time and to not have any contact whatsoever with her.

But the vidoes and messages did not stop.  Pratt said she would let the court know that he was violating the injuction, but she felt she was getting the runaround.
