A judge has entered not guilty pleas for two brothers charged with stabbing their parents and three siblings to death at their Oklahoma home last month.

Eighteen-year-old Robert Bever and his 16-year-old brother, Michael, appeared in court Monday via video.

A judge entered not guilty pleas on their behalf and scheduled an Oct. 28 preliminary hearing.

Lawyers for the two declined comment, saying it was too early to talk about the case.

The brothers were charged Friday with five counts of first-degree murder each in the July 22 deaths of their parents, two brothers and a sister at their home in Broken Arrow, a Tulsa suburb.

They are also accused of stabbing their 13-year-old sister, who survived. A toddler was found in the home unharmed.
