PEORIA, Ill. -- It appears Wednesday is the day Jason Harris will testify against his brother in the Christopher Harris' mass murder trial.

On Tuesday, prosecutors described several fingerprints found at the murder scene that match those of Christopher Harris.

The 34-year-old is charged with brutally killing Rick and Ruth Gee and three of their children at their Beason home in 2009, and the attempted murder of a fourth child.

A state crime lab expert testified that six fingerprints, matching those of Christopher Harris, were found in one of the victims bedrooms. Tracy Moore also testified that a similar fingerprint matching Harris' was also found on the cover of a laptop stolen from the home the night of the murders.

Another state crime lab expert provided analysis of two pairs of tennis shoes. Authorities found one pair near a bridge outside of Beason a few weeks after the murders, another pair was obtained from Harris during a search.

She was not able to positively link the shoe patterns inside the home with those of Harris', but said there were similarities.
