Looking for a crime/thriller movie I watched around 2021 — help identify it

I’ve been trying to find the title of an American crime/detective movie I saw (probably released between 2010 and 2019, could be off by a few years). It had strong investigative and dramatic elements, especially near the end, and took place in a gloomy small town.

Here’s what I remember:

• The main character is a female detective, possibly in her late 30s or early 40s. She’s experienced and a bit jaded.
• At some point in the story, a Black sheriff or police chief tells her the case has been cold for a long time, with no leads.
• She’s assigned a young male partner — tall, skinny, around 25–28, with styled or swept-up hair.
• At first, she doesn’t like him much, but over time she grows to respect his intellect and sharp mind during the investigation.
• Together, they trace the case to a house owned by the suspected killer — someone the police hadn’t been able to catch.
• During the raid on the house, the young partner recklessly rushes in and gets shot in the forehead — he dies instantly.
• The woman is then left to face the killer alone inside the house. The atmosphere becomes very tense and suspenseful.
• The killer is a large, disturbing man who hides in different rooms and tries to lure her in.
• She also has to deal with his dog, which he sics on her — though I may be misremembering this detail.
• Despite the danger, she manages to outsmart and capture the killer.

Some additional emotional details I recall:

• Before the final raid, the young partner confessed his feelings to the female detective. Despite their age difference, he kissed her near a bridge or by a river while standing close to the railing.

Possibly the killer did something with women’s skin and hid bodies in his basement — again, not 100% sure.

This might not have been a very popular or successful film — maybe low budget or straight-to-streaming, so I’m open to obscure suggestions. I’ve searched everywhere but still haven’t found it.

If this sounds familiar to anyone, I’d really appreciate the help 🙏
