Same article but updated a little this morning with how they theorize the crime occurred.
Momoffourboys and los2188, I am so impressed. You were on it! And I live in the area
"According to a sworn complaint obtained by The Sun through a public records request, police believe Armas killed Brim after an argument, then loaded her body in the trunk of her car and drove her to a location where he disposed of her body.
They believe he then tried to get rid of the knife that was likely used as the murder weapon, and drove Brim's car to his mother's home, where he cleaned it and burned bloody floor mats and Brim's bloodied clothes, the complaint said.
After Armas learned Brim had been reported missing, police say he made arrangements to have the car destroyed.
Video surveillance footage showed Armas leaving a silver sedan — Brim's car — in the parking lot of a Wal-Mart Supercenter the night of Jan. 19 and returning to retrieve it four days later.
The sedan ended up at a garage and was supposed to be sold for parts, then crushed. Before that could happen, a tow truck driver turned the car over to police, who searched it and found blood evidence in the trunk."
