McKEE, Ky. — Police say a man killed a 5-year-old boy and brutally attacked his mother, pushing her off a 77-foot cliff in eastern Kentucky, over $200.

Kentucky State Police detective Charles Brandenburg testified Monday during a preliminary hearing in Jackson County District Court that 41-year-old Lonnie Belt thought the boy's stepfather had stolen the money from him. The stepfather, David Durham, has denied the accusation.

Brandenburg testified that Belt told police he had planned to hold the two hostage until the money was repaid. The detective said he didn't know why Belt instead severely injured 29-year-old Jessica Durham on Sept. 8, striking her in the back of the head with a metal object, before taking her to different site, where he repeatedly beat her, reports CBS affiliate WKYT.

A judge sent the case to the grand jury. Belt faces multiple charges, including murder.
