A Randolph County judge denied a bond reduction Monday for 20-year-old Alyana Mason, one of several suspects charged in the death of 16-year-old Kayla Huff of Moberly.
Mason remains jailed without bond on murder and kidnapping charges.
Prosecutors recently upgraded charges against Mason and 19-year-old Hunter Ames to first-degree murder.
Three other defendants had bond hearings delayed until June 1 after appearing without attorneys.
A fifth suspect, 24-year-old Skyler Powell, was arraigned Monday on a charge of hindering prosecution.
Huff disappeared May 6 and was found dead a week later in the Rudolf Bennitt Conservation Area.
A celebration of life is scheduled Wednesday in Moberly.
