A second defendant in two days has been convicted after a plea in connection with a February attempted robbery of a man in Oread neighborhood.

Clinton Dubray, 18, of Lawrence, pleaded no contest to attempted aggravated robbery and obstruction Thursday morning in front of District Judge Sally Pokorny. Co-defendant Franklin J. Spottedtail, 20, also of Lawrence, pleaded guilty to the same charges Wednesday.

Assistant district attorney Michael Allen said prosecutors had evidence that Dubray tried to use a handgun to rob a 43-year-old Lawrence man who was walking at 3 a.m. Feb. 26 in the 1100 block of Tennessee Street. Spottedtail admitted Wednesday he grabbed the man’s arms while Dubray tried to hold him up, but a Lawrence police officer drove by and thwarted the robbery attempt.

Both men ran away but were later arrested and charged in the case.

Defense attorney Napoleon Crews said his side would ask Pokorny to sentence Dubray to probation. Allen said prosecutors plan to ask for prison time.

Pokorny said Dubray could face anywhere from 31 months to 136 months in prison on the attempted robbery count. She is scheduled to sentence Dubray at 1:30 p.m. May 24 and Spottedtail at 11 a.m. June 6.
