Have you established which route NC travelled back to Lagos from Rua Direita?
No I have not, but I would say these ~20-25 missing minutes was a minimum.
He said he left for his resident at 20:45 but she said they went to the reception at 21:00 to collect a service vehicle and travelled home in separate vehicles and arrived at about 21:15.
Was it she who came home at 21:15?
Or did both arrived at home at 21:15?
Did they both drove the same route on their way home?
A couple of more odd things in his statement is that he was talking about himself only.
No mention at all from him that his girlfriend was with him that evening when did the job at the OC.
No mention from him that they went together in same car from their home in Lagos to the OC.
Was it already planned before they left home that they would stop to collect a service vehicle on their way home?
If not, why did not NC drove the car himself from their home to the OC?
Was there a special reason why she had to drive him to perform a small maintenance job?
I've a theory(or questions maybe) why both of them left for OC in the same car and why he was only talking about himself.
