Twenty-eight-year-old Brandon Charles, of Ypsilanti Township, was supposed to testify in a road-rage shooting, but was shot and killed in a West Willow driveway before he could.

Sophie Peak, of Ypsilanti, subsequently

testified in the homicide case

, but now it turns out she lied.

In the complex case’s latest twist, 19-year-old Peak was arraigned on one count of perjury Thursday from the Washtenaw County Jail, where she is serving time on a robbery charge.

Prosecutors allege she lied about who was present at the shooting, which took place Jan. 27 in the 600 block of Calder Avenue of Ypsilanti Township.

“We subsequently learned she was not there,” said Assistant Washtenaw County Prosecutor Blaine Longsworth during a bond argument.

One of the main suspects in the homicide, 30-year-old Willie Lee Wimberly, wasn’t present when the shooting took place either, according to Longsworth. Peak was the key witness at a preliminary examination in April for Wimberly and her one-time boyfriend, Avantis Parker, who has already pleaded guilty to second-degree murder in the case.

At that hearing, which ended with Wimberly and Parker being bound over to circuit court, Peak wove a tale about the events leading up to Charles being shot to death while sitting in a parked car. Peak testified she and Parker ate dinner, then went to a home in Inkster where the plot to kill Charles was hatched.

Avantis Parker and Willie Wimberly

Wimberly and another man are accused of shooting at Charles and his girlfriend in a road rage incident on a Detroit freeway Jan. 1. Charles was set to testify the day after he was killed. Peak testified Wimberly offered Charles $10,000 to not testify, but that Charles demanded more.

At the Inkster house with Peak and Parker were Wimberly and Parker’s half-brother, Terrence, 21, who was eventually charged with murder in the case, but not until months after Peak’s testimony.

Peak said she got in the car with Wimberly and Terrence while Avantis drove the four of them to the home on Calder Avenue. It was initially believed Wimberly pulled the trigger. Charles died from five shots — one directly through the heart and four more in the buttocks.

Terrence Parker and Lawrence Mathews

Prosecutors on Thursday said there is video footage of Wimberly at a store at the time of the shooting.

In October, shortly after Parker took a plea deal, his half-brother and 24-year-old Lawrence Mathews were charged in the shooting.

According to court records, Mathews pleaded guilty Nov. 7 to second-degree murder and intimidating a witness in exchange for the dismissal for several other felonies. He is scheduled to be sentenced Dec. 7.

Another preliminary examination is scheduled Friday for Wimberly. Terrence Parker will be his co-defendant at the hearing.

Magistrate Thomas Truesdell ordered Peak be held at the Washtenaw County Jail on $100,000 cash bond. She was scheduled to be released from jail in 13 days. She was serving time for an unrelated robbery she committed with Avantis Parker.
