Movie about a killer who kills one guy by tying an iron on his face and turning it on

Hi!
I watched part of this movie and caught a glimpse of that scene in the title.
After turning it on and a few seconds later, the guy (with the iron on his face) starts waking up to the heat. The killer, goes outside to take out the trash but when he returns, the other guy is on the floor dead with the iron still burning on his face
Additionally, I recall a jogger girl going in the house to try and help another girl but the jogger gets her throat slit.
