Prosecutors in the Denny Ross murder trial began to introduce DNA evidence in court Wednesday.

News Channel 5 reports the state feels this evidence is crucial to the argument Ross murdered 18-year old Hannah Hill in 1999.

A former Ohio BCI (Bureau of Criminal Identification and Investigation) agent testified that a blood spot the size of a pencil eraser was found on an inside pocket of Hill's corduroy pants.

Prosecutors also said other DNA found on Hill's clothing, in the trunk of her car and under her fingernails paints Ross as the killer.

Hill was found strangled and stuffed in the trunk of her car  on a  residential street in Ellet six days after she was reported missing.

Articles of clothing belonging to Hill were discovered in a garbage bag just outside Ross apartment in Springfield Township.

Opening statements from the defense state that Hill's DNA was not found in Denny Ross apartment, where authorities believe the murder took place 13 years ago.

Denny Ross has maintained his innocence.

The trial has gone on for the past three weeks and could last an additional three to five more weeks.

The case ended in a mistrial in 2000, where DNA evidence was not available.
