BOISE -- Patrick Zacharias is now accused of the murder of Kay Lynn Jackson in April 1998. Her body was found under the Americana Bridge on the Greenbelt.
Zacharias is currently serving a life sentence for lewd conduct with a minor. He was sentenced for that crime back in 2007, but that certainly is not the only thing on his criminal record.
According to his court records, Patrick Zacharias has been arrested many times, once just days after Jackson's death.
In court Wednesday, Patrick Zacharias appeared on the newly filed murder charge, accused of raping and murdering 22-year-old Kay Lynn Jackson 15 years ago.
Looking at Zacharias's criminal past, he has been in trouble with the law a number of times. Just days after Jackson's death, court filings show he was accused of grand theft.
His rap sheet includes several other theft and burglary cases, but what stands out and landed him in prison for life was a lewd conduct case from 2006.
According to court documents obtained by KTVB, Zacharias tried to force himself on an 11-year-old girl threatening to kill her if she didn't comply with his demands. She was able to escape to a neighbor's house, but was injured.
After Judge Cheri Copsey sentenced Zacharias to life in prison without parole, his attorney asked for a new sentence.
The judge said no, writing that evaluations showed he has a "high risk to re-offend" and has a "... highly exploitative behavior pattern and lifestyle with an antisocial personality. He rationalizes his behavior and feels victimized."
The judge also said society needed to be protected from him committing possible future similar crimes, writing: "There is a need to deter both Zacharias and others from such behavior. Furthermore, the Court found that the magnitude of this crime outweighed Zacharias's character and background."
Again, this was all 8 years after Jackson was found dead near the Boise River, but it was during his prison time on that case that a sample of Zacharias's DNA was taken and entered into a nation-wide database. It was that DNA police say broke this case.
The lead detective in the Jackson case, Mark Ayotte, is said to have kept the file on his desk for the last 15 years, following thousands of leads. He was also the lead detective on the Robert Manwill murder case, in which the 8-year-old's mom and her boyfriend were convicted.
Zacharias has another court date on Friday, May 3, where he may enter a plea.
The maximum sentence for 1st-degree murder in Idaho is life in prison, unless prosecutors seek the death penalty. They say they have not decided if they'll do that, yet.
