<human>: Give me a shortened version of the text

Some one "borrowed" my computer and went through all my emails and messages. When I started telling people I was filing a police report it suddenly showed back up when I was at work, with the browsing history deleted. Luckily I had it synced with my phone so I knew what they were doing. I have strong suspicions of who it was, but would rather them not get in trouble legally, I just want to be sure so I know who to remove from my life. I already used an IP tracker but all it told me was the service provider.
<bot>: somone took my computer and went through my email. I have the IP address and want to know who it was without involving police.
