Crows, Owls, Blackbirds what do they mean at this time in my life?

A Felony occur at my home last Friday, the 6th, night and there is an investigation going on. Well on the following Monday, the 9th, night around 3:35am there was an Owl right outside my bedroom window. We have live here for 5 years and have never sen or heard an Owl before. I was gone several min later. Today, Thursday 12th, as I was walking to my truck for lunch, at work, there was 4 large Crows and 2 blackbirds in the bed of my truck, just standing there. When they all saw me they flew away cawing. What does all this mean? I am half American Indian if that helps.
