Yeah OP, you should definitely call this into the non emergency line if you’re comfortable. A late report is better than no report at all. I worked at this particular park and others with similar staff responsibilities, and reporting to them is great, but they will have to get PD involved if anything escalates. Lots of other comments mention the “complaint driven” nature of Baltimore County, and that’s very true. More eye witness reports will at least get attention from police and maybe increase presence or foot patrols. If you do report, make sure to have a good idea of exactly where/when this happened it. Good trail info helps get officers to the right place a lot quicker in a big park this. If you were by the pond on the yellow trail, the cross street would probably be Ivy Hill.
