An argument ensued when the suspect called the victim a derogatory name. Another employee then interjected taking the argument outside. Nanakuli Wendy’s employee dead after double stabbing “Reportedly, Victim One punched the suspect who in turn stabbed Victim One and Victim Two,” said HPD Lt. Deena Thoemmes. “Victim Two attempted to help when he was stabbed as well.” The first victim, a 22-year-old man, was taken to the hospital where he died of his injuries, according to HPD. The second victim, a 44-year-old man, remains in serious condition. The suspect was arrested at the scene for Second Degree Murder and Second Degree Attempted Murder, per HPD. He remains in custody. The stabbing is just one example of the many challenges retail workers continue to face, according to Retail Merchants of Hawaii. "Violent crime has increased because it kind of entitles the thieves to feel that they have the right to go into a store and take what they want without paying," stated former HPD Deputy Chief of Police, John McCarthy. HPD said the public should avoid confrontation with unruly customers, but RMH said employees are becoming frustrated. "Employees are getting frustrated because they see the same people coming in every day, shoplifting and stealing, and they can't do anything about it," said Tina Yamaki, RMH President. McCarthy adds employees need more training than before to stay protected. "30, 40, 50 years ago, you brought an employee and you trained them with job skills. Now you've got to train them with people skills. You've got to teach them about active shooters. You have to talk to them about robberies, burglaries, theft and what they do or shouldn't do in accordance with company policy," said McCarthy.

"At what point do you realize this is not going to end well, it's not going to go any further, get any better? Try to train them to teach them to look for signs, and the police should be called at the earliest possible time," stated McCarthy.
