(CBS/AP) A janitor was charged Friday with murdering Northern California elementary school principal Sam LaCara, who was shot after the suspect was sent home over a personnel dispute.

John Luebbers, 44, was charged after telling investigators he shot the 50-year-old LaCara twice in the office at Louisiana Schnell Elementary School in Placerville, police said.

Luebbers pleaded not guilty at his arraignment. he is due back in court next month.

School officials said Luebbers had been sent home for the day after the two friends had a dispute Wednesday about the district's selection of a new nighttime custodian.

David Weiner, an attorney and friend of Luebbers' family, said the suspect was not in good health when he visited him in jail.

"He has medical problems. He suffers from some extreme diabetic problems and associated high blood pressure," Weiner said. "He's not in good shape at all."

No children were hurt in the attack, but police said one student may have witnessed the shooting about 50 miles east of Sacramento.

Students returned to school Friday for the first time since the shooting that prompted a lockdown of the 400-student campus.

A memorial service for LaCara is scheduled for Tuesday.
