CLEVELAND (AP) - A Cleveland man has pleaded not guilty to nearly 300 counts including aggravated murder and rape charges that date back to the mid-1990s.

Elias Acevedo appeared in court Monday where a Cuyahoga County judge set his bond at $5 million.

The 49-year-old Acevedo is accused in the death of his neighbor in 1994 and another woman in 1995.

Authorities last week identified human remains found in Cleveland as those of the second woman who was pregnant and 18 when she disappeared in 1995.

Authorities in Cleveland have been looking into the disappearances of women in the city following the escape of three women held captive for a decade in a home owned by Ariel Castro.
