Investigators are looking into the possibility of Lorich taking his own life since there are no signs of forced entry in his apartment. Authorities have not found a suicide note so far.

Lorich lived in an Upper East Side apartment on Park Avenue with his wife and three daughters. At the time, Lorich's wife was not present inside the house. She was out playing tennis.

Although the police did not go into the details, they did reveal that Lorich was going through some kind of "personal stress" in recent times.

In fact, in January of 2010, Dr. Lorich sent a detailed email to a confidant which ended up getting forwarded to Cheryl Mills who was Counselor and Chief of Staff to Secretary of State Hillary Clinton at the time before being forwarded on again to Secretary of State Hillary Clinton.

The doctor's correspondence, provided by Wikileaks, was critical of how the situation in Haiti was being handled.

"Disaster management on the ground was nonexistent," the doctor wrote. " Cheerios on the tarmac are not getting it done on these patients which clearly would be savable if good care could urgently be provided."

However, the email was only a precursor to the bombshell the doctor dropped publically just days later on Jan. 25, 2010, in a piece for CNN titled "Doctors: Haiti medical situation shameful" which detailed the conditions overseas and again the doctor took veiled shots at the Clinton Foundation.

"Once we arrived, we saw a severely damaged hospital with no running water and only limited electrical power, supplied by a generator. Surgeries were being performed in the equivalent of a large storage closet, where amputations were performed with hacksaws," the doctor wrote. "This facility could not nearly accommodate our equipment nor our expertise to treat the volume of injuries we saw."
