But as she became sicker and he had to face the fact that he'd soon be a widower, he retreated more into himself and became quieter.

Joan Schwartz's death crushed the guy.

Their kids were in their late teens and early 20s at the time, and raising them now fell squarely on his shoulders.

Even when Joan was alive, the family had its share of rocky times.

But once she was gone, Clara, the youngest, took it the hardest.

That's Dr. Katherine Ramsland, a forensic psychologist, who has written about this case.

She's talking about Clara Schwartz, who actually found her mother's body.

Dr. Schwartz, a single father, struggled with how to deal with Clara and get her through high school.

They lived together then on the farm where there was plenty to do and he expected her, as most parents would, to step up.

Dr. Schwartz's co-worker Terry says as Dr. Schwartz's kids grew older, he opened up about how proud he was of Jesse, the oldest, Michelle, the middle child, and even the youngest, Clara.

It always seemed to go back to Jones' death and Schwartz having to raise them alone.

He strove to get the best out of them all.

And being an overachiever himself, expected it.

In all of the investigations I have been involved in, you have to consider the victim's chosen career path, especially when someone has high visibility within what is a high profile company.

We saw this recently with the healthcare CEO murdered on the streets of New York.

so a question came up was dr schwartz targeted after all he knew big players within the scientific world hundreds of millions of dollars were at stake had he been involved in research or something else that could have gotten him killed

Detective Locke was not ruling any possibility out.

Locke's next point of evidence gathering was the grim task of attending the autopsy and seeing what unusual details of the crime the postmortem revealed.

So Schwartz fought with his attacker, which meant there was going to be DNA.

With over 700 autopsies under her belt, Dr. Carolyn Revercombe noticed immediately after she started her cursory inspection of Schwartz's body that he had suffered two stab wounds to his neck that went entirely through one side of his body and out the other side.
