Given how much blood was by the front door, doesn’t that make the delayed 911 call more suspicious? I’m just trying to imagine going to my mom’s house after she missed a regular activity, finding her gone and seeing blood outside her front door and doing anything beyond calling my local siblings and then 911. Maybe I take 10 minutes to call close friends to see if someone helped her get to a hospital. I think my immediate suspicion would be a head injury and then wandering off, so time would be of the essence. I’d rather be embarrassed at rushing to call for help if she innocently turned up than waste precious time.
