We are from the UK and thus time format is 24 hour. The picture evidence show photos time stamps at 06.30- 06.55 on the 30th . However the Time of death was 22.00 on the 30th. (See attached). This indicates the murder took place early in the morning of the 30th as evidence was gathered early morning.
Although crime time was not actually given solution was AFTER 20.00. This is illogical if the photos were taken 18 hours BEFORE??
Written witness reports also confuse this by one saying a business CLOSED at 11.00 (in the morning - 'should say 23.00'), but people were taking breaks at 20.00 (in the evening) etc.
Suggest you get the time format consistent throughout all the documentation and state the format used in the instructions.
Also, final solutions mentions a 'Brother' has a gun - Not mentioned in ANY documentation, so how could the Police have known??
Anyway it was fun and all the 'stuff' was good quality print. Well Done.
