Investigators described it as a one-in-a-million chance. A tiny manufacturing flaw on an envelope exposed a murderer who was willing to kill innocent victims to get at the one person he wanted dead.

It was a typical Monday morning at the Transamerica title insurance Company in Tempe, Arizona.

There were only four employees, all friends,

who spent their work days processing paperwork.

46-year-old Julie Williams had been working at Transamerica for two months.

She walks down to the bathroom, she goes into the bathroom bathroom and the people are kind of worried about her.

The other employees were baffled.

They got some water out of the water cooler and tasted it.

They found Julie unconscious, completely unresponsive.

Paramedics arrived minutes later and rushed her to the hospital. She was in a coma,
