A Douglas County jury Tuesday afternoon began hearing evidence in the case of a Kansas City, Mo., man accused of taking part in a 2010 Lawrence robbery.

Prosecutors accuse 30-year-old Matthew Thomas Garren of pointing a gun at the back of a 20-year-old Lawrence man’s head the night of Jan. 19, 2010, during a robbery. Ronald Broschart, 23, was convicted last year of one count of robbery in the case and sentenced to 44 months in prison.

Garren’s defense attorney, Napoleon Crews, questioned the credibility of witnesses and the victim in the case and what they told police about his client’s involvement.

“(Garren) was not there to rob anyone,” Crews told jurors.

The victim in the case, 22-year-old Lonnie Schaefer, testified Tuesday that he had met up with Broschart that night because he thought he was going to buy marijuana.

He got into a van that later pulled over in the 1500 block of Haskell Avenue and said Broschart pulled a gun and demanded Schaefer’s wallet before they took more than $1,600 from him. He also said he felt someone put an object he assumed was a gun against the back of his head.

Schaefer faces aggravated robbery and aggravated arson charges in a separate case because prosecutors accuse him of participating in a Dec. 13 armed robbery at Walmart, 3300 Iowa.
