Help!!!

so for days i have this episode stuck in my mind that i listened to when i first started listening to CJ. i don't remember that much if it anymore sadly, i do remember that it was a murder case and it was solved, i think it was a woman who got killed by a "family" friend (like friend of her and her spouse?) or someone fairly close like that that's all i remember but i can't get it out of my head and searched and searched for it (oh and it wasn't karen gregory)
