Kalonniann Clark went to Denver police on Dec. 4, 2006, with two new pieces of information about an attempt to kill her more than a year before.

She'd been getting threatening phone calls from the girlfriend of the man about to go on trial for the drive-by shooting, Clark told detectives. She said she now remembered who was driving 18 months earlier, when Brian Hicks allegedly shot at her.

With the new information, Denver police got arrest warrants for the girlfriend, Kimaya James, and the accused driver, Benjamin Cordell Thomas.

Two days later, Clark was dead, gunned down outside her Cherry Creek apartment.

Her unsolved slaying is one of 11 - including the New Year's Day homicide of Denver Bronco Darrent Williams - that authorities say may be connected to a group of gang members known as the "Elite Eight" and other members of the Tre Tre Crips gang.

The group, which included Hicks and Thomas, sold large quantities of cocaine, an investigator for the Metro Gang Task Force testified in court last month. He also said the group shot people who got in their way and intimidated witness who might offer evidence against them.

Prosecutors hope the arrest of several group members on drug charges in April will lead to charges in the killings.

Authorities have not released the names of the other victims whose deaths they believe may be connected to the group. Many of the suspects are behind bars. But the Rev. Leon Kelly, director of Open Door Youth Gang Alternatives, can rattle off a list of possibilities.

Among them are Derrek Davonte Ward, an 18-year-old man shot in the back of the head while leaving a sweet sixteen party in December, and Bruce Harrell, a 21-year-old shot along with another man while driving near 29th and Welton streets in January 2006.

Clark's boyfriend told police Clark was shot after two men forced their way into their apartment late on the evening of Dec. 6, demanding drugs and money.

Both Hicks and Thomas were in jail when Clark was killed. Her killing remains unsolved.

James went on trial earlier this summer for intimidation of a witness, but a jury was not able to reach a unanimous verdict. Meanwhile, the charges against Thomas were dropped because prosecutors said they did not have enough evidence against him.

Hicks, who is in jail on federal drug charges, is still awaiting trial on the attempted murder. It has been rescheduled for Sept.10, though his attorney has filed a motion to dismiss the case, saying the "essential witness" - Kalonniann Clark - is unavailable.
