WATERLOO - A Waterloo gang member serving prison time in a December slaying said a prosecutor tried to get him to make up testimony against a man charged in a July 2006 nightclub shooting.

Shean Henry Holmes, 20, was the last defense witness in Jeffrey "J-Rich" Duane Smith's murder trial Wednesday.

Police allege Smith, 21, shot Tonyeah Jackson, 27, with a 9mm handgun at Club Crystyles. Jackson allegedly hit Smith earlier that day as Smith argued with a girlfriend who was Jackson's cousin.

The defense used Holmes' testimony to cast doubt on an earlier jailhouse witness who claimed Smith admitted to the killing and to show that police did little to investigate people found at a Woodmayr Drive house with 9mm ammo and drugs shortly after the shooting.

Holmes admitted he was a member of the Southside street gang and is doing 26 years at Fort Madison for manslaughter charges in the death of Jasmine Mills, 18.

Holmes said Assistant County Attorney Joel Dalrymple offered to put money on his jail commissary account and dismiss weapons charges Holmes was facing at the time (the manslaughter charge came later).

"He wanted me to testify against Jeff Smith and make up something," Holmes told jurors. "I told him I couldn't help him."

He said Dalrymple, who isn't prosecuting Smith's case, wanted him to say he saw Smith with a gun equipped with a laser sight.

Holmes also was one of the people that police found at 1680 Woodmayr Drive shortly after the shooting.

Officers went to the home after finding a vehicle matching one description given for the getaway car in the driveway.

Police searched the home and located drugs, a .22-caliber pistol and three rounds of 9mm ammo. But they failed to find Smith at the house and apparently discounted the vehicle as a false lead in the homicide case.

No one in the house was ever charged in connection with the narcotics.

Holmes said he was watching Dontay Sanford and Martez Anderson play chess in the bedroom of the Woodmayr home when they got a call police were outside. He admitted he tried to hide from officers and later fled out the back door but was caught.

He said he had handled a 9mm pistol in the past by denied any connection to the ammo, gun and narcotics in the house.

Holmes said he had nothing to do with Jackson's death and said police didn't question him about the slaying or about drugs in the house.

Closing arguments in the case are scheduled to begin today.
