This is the part of that article I find most interesting....
"On Friday, police conducted a search of Matthew’s vehicle, a 1998 burnt orange Chrysler coupe, which was parked in front of his apartment. While police were there, an interaction with residents of the complex led police to seek a search warrant for Matthew’s apartment while he was inside, Pleasants said."
An interaction with residents led to the warrant for the apartment? What kind of interaction could that have been?!? Intriguing.... I wonder who told them and what they told!
