The man Lansing police call a serial killer is now facing charges in a second murder.

Matthew Macon appeared for a video arraignment Wednesday. His only words were to confirm his name and say he understands the charges against him.

Already charged in the murder of Sandra Eichorn and for the assault of a woman in her Jones Street home, Macon is now charged with murder, torture and criminal sexual conduct in the death of Karen Delgado-Yates.

"We received information yesterday that gave us enough to believe it was appropriate to charge at this time," Ingham County Prosecuting Attorney Stuart Dunnings III said Wednesday.

Delgado-Yates was found severely hurt in a home on Hickory Street August 29. Investigators say she died on the way to the hospital.

Macon's attorney, Mike O'Briant, said his client was "surprised" by the charges.

Now O'Briant is asking the court to close his preliminary examination, the hearing during which prosecutors present their evidence in a case and a judge determines whether it should go to trial.

"The underlying reason is my client wants a fair trial, that he won't be prejudged until all the evidence is out in front of a jury," O'Briant said.

A closed preliminary exam would mean no reporters would be allowed in. It's designed to prevent potential jurors from hearing about evidence before a trial.

"Normally, preliminary exams are open and there's a good reason why they are," Dunnings said, but added it was "a determination for the judge."

Delgado-Yates was the last of five women murdered this summer in Lansing. Shortly after she died, investigators accused Macon of those murders, the Jones Street assault and a December 2004 murder.

"The Lansing police continue to work with our office around the clock to solve the brutal and senseless string of slayings that struck in the past summer," Dunnings said Wednesday.

Macon is also believed to be a suspect in the death of Lansing Community College Professor Carolyn Kronenberg.

Dunnings would not say whether more charges are coming or when they would come.
