A Douglas County judge ruled Tuesday that a 20-year-old Lawrence man, accused of assaulting a Lawrence police officer, will go to trial on a more severe count than he was originally charged with.

After a preliminary hearing, assistant district attorney Deborah Moody asked District Judge Kay Huff to bind Louis G. Galloway Jr. over on aggravated battery of a law enforcement officer causing great bodily harm.

Prosecutors accuse Galloway of injuring Lawrence police officer Jonathon Evinger during a Feb. 26 traffic stop in the 2100 block of West 26th Street. Prosecutors said Evinger, who was briefly hospitalized, had a concussion. Witnesses who testified Tuesday included Evinger and officer Stephen Ramsdell.

Galloway is also accused of two counts of misdemeanor assault against Ramsdell. He also faces misdemeanor obstruction charges and a theft charge because he was accused of stealing 14 cases of beer from Holiday Inn Lawrence, 200 McDonald Drive.

Galloway remains in jail on $75,000 bond. A trial is scheduled for May 18.
