James Eric Davis Jr. was arrested after a manhunt and faces murder and gun charges in the Friday morning slayings of his father, Eric Davis Sr., and mother, Diva Davis.
"The gun was registered to his father, and. we saw for sure that [Davis] came from the parking lot into our residence hall with the gun and the father was upstairs at that time", Yeagley said. Davis Sr. was an Iraq war veteran and friends say the suspect's mother was a breast cancer survivor.
Davis Jr.'s father was a police officer in Bellwood, Illinois, which is just west of Chicago.
The parents have at least two other children, an older son and a younger daughter, according to Harvey.

"He said someone was out to hurt him, someone was out to harm him", Yeagley said, adding that when officers pressed Davis for more details, he was "extremely vague". Officers ultimately were not able to identify any risk, Yeagley said. Yeagley said that when officers determined that the person posed no threat - and reviewed video from the elevator that showed Davis Jr. and that person laughing - Davis Jr. said he was fine and was leaving campus Friday for spring break. She said she was concerned as well and she would be on her way to CMU right away.
The shooting happened Friday after James Eric Davis Jr.'s parents picked him up from that hospital and brought him to his dorm to pack up for spring break.
Hours later, officers spotted Davis in a dorm hallway with his suitcases, acting strangely, Yeagley said, and they asked him to call his parents, which he did.
Central Michigan University's Campbell Hall, March 2, 2018. Investigators have collected video and photos supporting the witness's statement, Yeagley said.
"Two individuals were fatally shot at Campbell Hall on campus this morning". But Yeagley said it wouldn't be "unusual or surprising" if no one was at the door, given it was spring break move-out day and students were coming in and out with their parents.
He brought it back to the room and allegedly shot his parents, police said. He then fled the scene on foot.
An officer asked Davis, Jr.to call his parents and Yeagley said the officer spoke to his mother about what they observed and shared concern that it might be drugs.
No students, faculty or staff were injured in the incident Friday, according to the university.
