During his initial appearance around 10:30 a.m. Thursday, Marlow did not enter any pleas, said Tami Ryan, chief assignment commissioner and judicial secretary. If he posts his $10 million bond, he is ordered to be on electronic home detention. His next hearing is Aug. 26, but Ryan said a Montgomery County grand jury is scheduled to review the case before then.

Butler Twp. Police Chief John Porter has said that law enforcement is still seeking information about Marlow. Anyone with information that can help the investigation is urged to call the FBI at 1-800-CALL-FBI (225-5324) or Miami Valley CrimeStoppers at 937-222-STOP (7867).

An incident report released Tuesday by the Butler Twp. Police Department indicated a handgun was used to shoot the victims.

Daryl McCormick, special agent in charge of the Bureau of Alcohol, Tobacco, Firearms and Explosives Columbus Field Office, said last week that it was still under investigation how Marlow acquired the gun used in the quadruple shooting, including whether it was stolen, a straw purchase or a third-party transfer.
