SHANNON PETTYPIECE, BLOOMBERG:

Well, basically his mother had been trying for months to get this man, who is in his 30s, who had been hearing voices, having paranoia, thinking there were drones flying overhead, the CIA was in his apartment.

Everyone knew something was wrong. He had been hospitalized. They've been to the emergency room.

But his family says they just couldn't get him an appointment with a psychiatrist in time to keep him on the medication he needed. Either doctors didn't take their insurance, they just wouldn't return their calls, they had months-long wait, or they didn't want to see him because he was a tough patient, he had history of substance abuse, he had paranoia. He was a difficult case. Doctors prefer an easier case.

So, after all of this, you know, his mother, his friends, his family trying, they did finally get him an appointment and the medication ran out. And, unfortunately, it ended very tragically. He murdered his mother with a kitchen knife. And everybody in the aftermath was saying, how could something like this happen? How could a man with family support, in a suburb of New York City, not be able to get help?

And one of the main reasons is because you have such a limited number of doctors willing to take the hard cases and take people with insurance.
