Of course I knew who Murtala Mohammed was. He was that ominous head on the twenty naira note. The airport in Lagos was named after him. The long bridge in Lokoja also bore his name. I knew his middle name was Ramat. As a child, my school once went on an excursion to the museum in Lagos and we had been shown the Peugeot car he was being driven in on the day the bullet of a lone shooter took life out of him. I knew that the name of this shooter was Dimka. I knew that after his death, Obasanjo took over power. I knew he took the first step towards moving the Federal Capital to Abuja. I knew he died in 1976. All the options before me bore 1976. But I did not know the exact day he died...
