I am sure the police said they were able to rule him out due to credit card reciepts & his mobile phone records, but dont be fooled by that. There are many tricks you can do with a mobile phone, here is one i know of - if you switch your mobile off it sends a signal out to the network provider informing them you have switched it off, therefore if somebody rings you it gives the message "we are sorry, this mobile phone is currently switched off" , however if you pull the battery of the back the phone it is unable to send a signal out to the service provider, so when somebody calls the phone it gives the alternate message "we are sorry, this mobile phone is unavailable" making the caller think you have lost the signal Basically the service provider assumes you have lost your signal ! Could the police of been wrong footed by GR taking the battery of his mobile after travelling a short distance & then returning to murder JY ?? You cant rule it out.
