The Plainfield teen charged with killing his parents at Central Michigan University last week appeared in court from his hospital bed for the first time Tuesday.
James Eric Davis Jr., 19, has been in the hospital since he was arrested Saturday. He appeared in the courtroom via video monitor for his arraignment.
Davis, Jr. is held on a $1 million bond and is charged with two counts of murder and a weapons charge.
Officials said he gunned down his father, James Eric Davis Sr., and his mother, Diva Davis, as they arrived to pick him up.
Davis, Jr. appeared in a hospital gown on the monitor and affirmed that he understood the charges against him.
An attorney for Davis, Jr.'s siblings spoke on their behalf.
"He is still loved, cared for and that they are not abandoning him," said family attorney Brent Hopper. "We don't know if that message is getting through to him. Does he feel abandoned because he hasn't been able to see anybody?"
Davis Sr. had been a longtime member of the Illinois Army National Guard, serving in the Iraq War and later as a recruiter, according to Illinois National Guard spokesman Lt. Col. Brad Leighton.
Their memorial services are scheduled for this weekend. A wake will be held from 4 to 8 p.m. at the Johnson Funeral Home at 5838 W. Division Street and funeral services will be held on Saturday, a family spokesperson said.
Representatives for the family said that they still have many questions, including why Davis, Jr. is still hospitalized and what caused him to commit the murder if he is responsible for it.
"This is not the Eric they know and love," said Hopper. "They have gotten no information regarding even the health of their brother."
Investigators have not reported whether drugs were found in Davis, Jr.'s system.
A spokesperson for the Davis family said in a statement, "On behalf of the Davis family they would like to thank the Bellwood Police Department and American Airlines for the support that they have extended to the family.
They would also like to thank the friends and coworkers of Sergeant Davis and Mrs. Davis for all of the prayers and condolences that they have extended.
In this very difficult time, the Davis family wants to express their love and support for Eric Junior whom they love and for him to know that he has not been abandoned. Further, they want it known that Eric Junior is their main focus.
They also ask for privacy at this most difficult time."
