There’s trouble in the grand jury room where witnesses are testifying about the circumstances surrounding Celeste Rivas‘ death … because at least one witness is so uncooperative she’s about to be arrested … TMZ has learned.

Here’s the way it went down … Beth Silverman, the deputy D.A. presenting the case in Los Angeles, came out into the hallway Wednesday afternoon and approached attorney Evan Jenness. She represents Robert Morgenroth, who manages singer D4vd.

Silverman told Jenness she was going to have the judge issue a “body attachment” … to force a female witness to testify before the grand jury. It appears the female witness was a no-show, and a visibly frustrated Silverman said she would have authorities take the female witness into custody and bring her to the courtroom.

We do not know who the female witness is, but it’s interesting she’s represented by the same lawyer as Morgenroth, who spent around 3 days testifying before the grand jury.

TMZ broke the story … Morgenroth was in the hallway on Monday, telling his lawyer things got tense in the grand jury room when Deputy D.A. Silverman pressed him on why he didn’t call police. He didn’t say what he knew that would make Silverman challenge him on not making the call, but he said he responded to her by saying he didn’t think it was his duty and he was trying to keep D4vd’s tour going.

Sherrone Moore is out of the job at Michigan … after the university announced he was fired for having an “inappropriate relationship with a staff member.”

The school confirmed the firing to TMZ Sports on Wednesday …  stating an investigation found “credible evidence” that Moore broke the rules with a fellow employee.

“U-M head football coach Sherrone Moore has been terminated, with cause, effective immediately,” the school said.

“This conduct constitutes a clear violation of University policy, and U-M maintains zero tolerance for such behavior.”

The sudden split was a shock at first, as Moore led the Wolverines to a 9-3 season. The record didn’t get them into the 12-team College Football Playoff, but they will face Texas in the Citrus Bowl in a few weeks.

Moore landed the HC job after being promoted to replace Jim Harbaugh, who left in January 2024 to coach the Los Angeles Chargers.

Apparently, Dynzell Sigers would rather die than be a short king … because the Georgia man went through months of pain and therapy to have his limbs dramatically lengthened to be taller.

Sigers stopped by “TMZ Live” Wednesday, and he revealed the procedure’s possible side effects include death. Check out the video … he talks about doctors breaking bones in the leg and inserting a rod to connect the broken pieces. Over time the rod is stretched, which also stretches the bone. Dynzell said each procedure requires at least 3 months of recovery.

Back in 2022, he was a young Navy medic who got rejected by a woman — for standing 5 feet 5 inches tall. Fast-forward to 2025, and he’s now a 6′ 1″ internet sensation after adding 8 inches to his frame with 2 risky procedures.
