Cecil Myers, father of Steenkamp's friend Gina, regarded Reeva as a daughter and the late model and media personality had been staying at his place in Johannesburg since September - her parents live more than 1000km away in Port Elizabeth.
He had a deal with Steenkamp as he did with his daughters that if they weren't coming home, they had to text him their plans.
About 10.30pm the night before she died, Steenkamp texted: "Hi guys, I'm too tired. It's too far to drive. I'm sleeping at Oscar's tonight. See you tomorrow."
Five hours later she had been shot three times through the bathroom window of Pistorius's Pretoria home, about an hour from her alternate accommodation.
The information came in Myers first interview with South Africa's City Press newspaper.
"I've got this thing with all three (Reeva, and his daughters, Kim and Gina), if they don't come home at night, they must text me. Then Reeva sent the (SMS) message: 'Hi guys, I'm too tired. It's too far to drive. I'm sleeping at Oscar's tonight. See you tomorrow."
"Tomorrow never dawned for her ... I have nightmares at night thinking how frightened she must have been. Can you imagine how terrified she was?
"That was the last SMS from her phone, probably about ten, ten thirty – the time they usually SMS."
