Introduction to the case

The criminal justice system often relies on legal technicalities to ensure fair trials and uphold justice. This is why it is often said that it is better to let 100 guilty people go free than for 1 innocent person to be unjustly convicted. However, these same technicalities can sometimes lead to notorious criminal walking free. In some high-profile cases, individuals with undeniable culpability have managed to evade punishment due to loopholes and oversights in the legal system. Let’s look at some of these instances

Derrick Hernandez Lack of speedy trial

The first person on our list is Derrick Hernandez. He was arrested by the Honolulu Police in 2014 for fatally stabbing a guy in a park by the sea in Maili. Hernandez faced a lengthy preliminary hearing before being finally released from custody in 2019 after the indictment dropped his second-degree murder accusation. Not getting a speedy preliminary trial caused issues. The province of Hawaii was left with little option but to drop the charges against him based on the technicality that since  arraignment took too long to begin

 Courtney Hackney’s Double Jeopardy

Holly Barnett,57, was reportedly battered to death in her own home by Courtney Hackney in May 2017. She was taken into custody and charged with the crime, but because of a few technicalities in the judicial process, the case was mismanaged. This would normally lead to another trial, but not in this instance. A procedural rule prevented Hackney from being tried again for the same offense because it would have violated the federal ban on double jeopardy which made Courtney walk free of her charges

“John’s” arrest Without a proper warrant

Christine Silawan, 16, was found dead from a stabbing after being sexually assaulted in March 2019. Her face was cut off, exposing her skull, and her remains were painstakingly dismembered. Her 17-year-old ex-boyfriend dubbed “John” by the media was taken into custody without delay because he was the alleged perpetrator. The suspect was released just as Christine’s funeral was getting underway. Since he was taken into custody without a warrant, his lawyer, Vincent Isle, successfully filed a motion to be released. He was taken to a safe home for his protection a few hours later.

Jose’s  Improper Jury Instruction

Kate Steinle, 32, was shot in the back in July 2015 by José Zárate while she was strolling around San Francisco’s Pier 14. Zárate said the gun inadvertently went off, but there was no doubt as to who fired it. After shooting Steinle, who passed away two hours later, Zárate was accused of first-degree murder, felon in possession of a firearm, and possession of illegal drugs. Following a trial spanning twelve days of testimony and five days of jury deliberations. He was found not guilty of all the charges except for possessing a firearm while a felon.

Waiving of Donald Clark’s Miranda rights

Willis Sample, 77, died as a result of a home invasion that Donald Clark acknowledged carrying out in 2016. Willis was tied up and robbed, and later on, he suffered a heart attack and passed away. Although the prosecution was simple, the victim’s case did not succeed. Clark was unable to consciously renounce his Miranda rights, even after it was determined that he was mentally competent to stand trial. The judge was forced to fully drop Clark’s murder case. As a result of this because it rendered  his confession null and worthless.
