March 15, 2019, 3pm Singapore time. Vera Ho felt that something was amiss. The Belitung native, who was back home visiting her parents, was on the phone with Herman Ho, her husband, back in Singapore. He had been complaining of a headache for three days now and it wasn't getting any better. If you don't feel good, just call a Grab and go to the hospital, she urged. "What's Grab? What are you talking about?" Herman mumbled, before he lapsed into unintelligible gibberish. Alarmed, Vera quickly dialled Herman's cousin in Punggol, begging him to send Herman to the hospital. The cousin immediately cabbed over to Vera and Herman's Sengkang house.
