Mismatch of killings and deaths

Hello! why the number of kills of the enemy team does not coincide with the number of deaths on my team and
why does not the number of murders match for my team (each separately in sum) with the total number of murders of my team
sorry, can’t upload screenshot

Like experience, a Hero has to be nearby to get credit for a kill or assist. If a Hero dies to a tower, fort, keep, minion, or mercenary and no enemy Hero is close, then no experience or credit.

If future you may want to ask your game play questions in the General Discussion forum.
