Two of the three suspects accused in the fatal shooting of Greater Memphis Chamber CEO Phil Trenary waived their rights to a preliminary hearing Tuesday and now their case will be sent to the grand jury for possible indictment on the murder charges.

Quandarius Richardson, 18, and McKinney Wright Jr., 22, are charged with first-degree murder in Trenary’s slaying. Wright’s cousin, 16-year-old Ranisha Wright, has also been charged in the homicide and she will be in Juvenile Court on Nov. 27 to see if she will be charged as an adult in connection with the slaying of the well-known business and civic leader.

Trenary, 64, was walking alone from a Memphis Chamber event on Sept. 27 when he was approached by one of the suspects in the 500 block of Front Street and shot in the back of the head, according to an arrest affidavit. The suspects fled in a stolen white pickup truck headed north on Front, police said.

The three suspects were arrested Sept. 29 and told police they were looking for people to possibly rob in the Downtown neighborhood, according to their affidavits.

Before the defendants waived their preliminary hearing, Judge Karen Massey told the media Tuesday that defendant Ranisha Wright could possibly testify during the hearing and not to take pictures or record her testimony. The prosecution was also set to call other witnesses, including several Memphis police officers who sat in the back of the courtroom waiting to be called to testify.

Dressed in blue jail scrubs, both Richardson and McKinney Wright answered “yes” when the judge asked them separately if it was their decision to waive their right to a preliminary hearing.

Defense attorneys Art Horne, who is representing Richardson, and Bill Massey, who is representing McKinney Wright, told reporters their clients’ decision to waive the hearing will help with their investigation in the case.

“Generally, it usually takes three to six months to get an indictment, so we probably would not have been able to get any of the information that we will get in the next few days for three to six months,” Horne said. “For this particular case, the investigation part is going to be key in our defense.''

Horne added after Tuesday’s brief court appearance that based on information he has received, he believes others may be involved in the death of Trenary, even though Memphis police said previously that no other arrests are expected in the case.

Initially, Memphis police said on Twitter that officers were searching for a man with dreadlocks driving the stolen Ford F-150 truck that was involved in the murder, but the suspects charged do not have dreadlocks.

“As the media has reported, there has been some identifications of people with dreadlocks and different descriptions of the alleged shooters,” Horne said. “We want that information in order to help us prepare going forward. The state has been working since Day 1 and we want to work and help defend our clients and we need that information.”

The case is not expected to be presented to the grand jury until January because of the upcoming holidays, Horne said. The grand jury will hear evidence and decide if the defendants will be indicted on the charges.

Annie Mae Stevenson, the grandmother of McKinney Wright, said she felt it was the right thing for him to do to waive his preliminary hearing.

“I just don’t think he did this,” she said about her 22-year-old grandson, who she said is developmentally delayed and has the mind of a teenager. “I hope the grand jury sees the truth."
