David Gray, Investment Banker, Chased Ex-Lover To London, Sent 176 Texts In 24 Hours

David Gray, a 28-year-old investment banker with JP Morgan, went to incredible lengths to get the attention of Daniela Rausnitz, his former lover.

So far, in fact, he pretty much redefined stalking.

Gray was convicted of harassing Rausnitz by a British court on Monday, after a long string of incidents. He had apparently showed up at the London hotel where she and her father were staying and told police he was an Israeli secret service agent who needed to speak with her urgently, according to the Daily Mail.

However, that was just a fraction of the bizarre behavior Gray exhibited.

Among a laundry list of personal space violations were accusations that he planted a tracking device in her phone, hacked her email, trespassed in her apartment using an old key, and falsely claimed his sister had died in an effort to get her attention.

According to the New York Post, Gray was even accused of visiting the same restaurant as Rausnitz the night before the trial began.

At one point Gray sent 176 text messages to Rausnitz in a 24 hour period.

Gray's behavior was also the reason for their separation. According to the Daily Mail, the two met in the investment banking division of JP Morgan in New York. Despite Gray's marriage, the two began an affair, and were at one point very intimate. However, Rausnitz ended it due to her lover's stifling behavior, and even transfered to London to escape him.

Gray was discharged from court on the condition that he keeps away from his former lover, according to Business Insider.

This is just one of the many ways the intense attitude of Wall Street seems to manifest itself in the personal lives of those involved. The somewhat insane behavior of Gray may be indicative of his extreme willingness to take risks, a mentality that has been identified by recent studies.

From this study:

Various studies have suggested that a certain kind of psychological profile gravitates toward the fast-paced, high-pressure environment of the trading floor -- and that this profile probably has more than a little in common with psychopathic personality, a clinical condition marked by gregariousness, impulsiveness, dishonesty and lack of empathy.
