Three 17-year-old boys accused of killing a young Mission Beach man who had answered a Craiglist ad to buy a computer appeared in court Aug. 16 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. The three defendants 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. The couple met the youths on Fleming Drive in Paradise Hills. Instead of landing a computer, the couple was robbed of their cash and cell phones at gunpoint. On Tuesday, the three defendants waived their right to have a speedy hearing as they appeared before a San Diego Superior Court judge. Rashon Jay Abernathy, Shaquille Jordan, and Seandell Lee Jones have pleaded not guilty. They remain in Juvenile Hall on $5 million bail. After Berki was robbed, he allegedly followed the robbers in his car as they turned into a cul-de-sac as Berki tried to obtain the robbers’ license number. Deputy District Attorney Kristian Trocha said Abernathy fired a shot through a windshield, striking Berki in the chest.?Berki died later that night. The three teens are being tried as adults. If convicted, they could be sentenced to 25 years to life.
