The preliminary trial for one of the people suspected of robbing two victims at gunpoint in the Church Street parking structure begins tomorrow.

Keith Mitchell-Lucas, a 23-year-old Ypsilanti resident, was arraigned Sept. 4 on four counts of felony.

Charges include possession of a firearm by a felon, which carries a possible sentence of five years in prison and/or $5,000 and possession of a firearm while committing a felony, which carries a possible sentence of two years.

In addition, he faces two counts of armed robbery, which can carry a minimum sentence of two years to life in prison.

His preliminary hearing is scheduled for tomorrow at 1 p.m. at the 22nd Circuit Court on Huron Street. Judge Lloyd Powell will oversee the examination.

The charges stem from a July 28 incident on the second floor of the Church Street parking structure. According to Department of Public Safety reports, two suspects, one of which had a small caliber handgun, stole a small amount of money from two people before fleeing on foot.

Mitchell-Lucas was arrested early Sept. 4 following a DPS investigation. DPS spokeswoman Diane Brown declined to comment on the investigation.

Brown said Sunday that there is a possibility the victims knew the men who robbed them.

The first suspect, allegedly Mitchell-Lucas, was described as being a black man, 19 to 20 years old and of stocky build.

The other suspect, who is described as being a 19- to 20-year-old black man standing 5-foot-9 to 5-foot-11 and weighing 160 pounds, has not yet been apprehended.

Brown said she could not comment on whether any other arrests will be made in the immediate future.

According to reports, he was not carrying a handgun.

A suspect in an unconnected attempted robbery Thursday, which also took place in the Church Street parking structure, has not been apprehended.

Despite the robberies that have taken place in the carport, some people who park there say they will continue to do so.

"It's the only place to park," said Ann Arbor resident Jared Smith, who uses the structure about once a week when visiting the South University area. "I've never had anything happen to me or my car here, and I always lock my doors, but I'll be more cautious."

The Church Street structure is one of the few carports in the campus area without a parking attendant on duty, but Smith still said he does not feel safety measures need to be increased.

"It's well-lit and well-trafficked. I always see cops around here," he said.

DPS officers patrol the carport whenever they file reports from incidents that occurred within the area, Brown said.

No other robberies have occurred at the carport over the last week, according to the DPS crime log.

However, a vehicle was broken into in the Fletcher Street carport Sept. 11., and personal property was stolen.
