Teleah, there is SO much great and powerful stuff here already, holy cow!

I genuinely wonder if you need the "putting a strain on her new marriage" in here at all. It does feel a little out of place and slows the pace down a touch, & I don't know how much it's adding to/is necessary for the logline itself.

I would suggest something like, "After the death of a rising star athlete, a grief-stricken mother obsessively works to expose a killer whose eye is on the young sports community."

Really really good start, though!

Angela Cristantello Thanks so much for your feedback! I like your suggestion!
