Three 17-year-old boys accused of killing a young Mission Beach man who answered a Craiglist ad to buy a computer appeared in court Tuesday and were given an Oct. 11 preliminary hearing date. They are charged with murder in the death of Garrett Berki, 18, of Mission Beach. He was a student at Mesa College and a 2010 graduate of La Jolla High School. They are also charged with shooting at an occupied vehicle and two counts of robbery involving Berki and his girlfriend. Berki and his girlfriend reportedly met with the defendants on May 11 after answering a Craigslist ad for a $600 computer. They met the youths on Fleming Drive in Paradise Hills and were instead robbed of their cash and cell phones at gunpoint. The defendants waived their right Tuesday to have a speedy hearing when they appeared before a San Diego Superior Court judge. Rashon Jay Abernathy, Shaquille Jordan and Seandell Lee Jones have pleaded not guilty and they remain in Juvenile Hall on $5 million bail. After Berki was robbed, he followed the robbers in his car as they turned into a cul-de-sac to try and get their license number. Deputy District Attorney Kristian Trocha said Abernathy fired a shot through a windshield and a bullet struck Berki in the chest. Berki died later that night. Trocha said all three teenagers are legally responsible for the murder under the felony murder rule. “All of them participated in the robbery. The murder was a part of the robbery,” said Trocha. They are being tried as adults. If convicted, they could be sentenced to 25 years to life.
