Jennifer (Jen) McCabe has already testified; she is not currently scheduled for a new future testimony date as of the latest widely reported coverage.

What has already happened

  • Jennifer McCabe testified in the first Karen Read trial on April 29, 2024.
  • She then took the stand again in the Karen Read murder retrial beginning on Tuesday, April 29, 2025, in Dedham, Massachusetts.
  • Coverage notes that she was called by the prosecution and her testimony and cross‑examination continued over multiple days at the end of April and into early May 2025.

So when people online ask “when is Jen McCabe testifying,” they are usually referring to:

  1. Her first appearance: April 29, 2024 (first trial).
  1. Her retrial appearances: starting April 29–30, 2025, with cross‑examination resuming on a Friday that same week.

Is there an upcoming date?

  • Public reporting focuses on those completed testimony dates in 2024 and 2025.
  • There is no clearly reported future calendar date for another Jen McCabe appearance beyond those trial days. If any new date exists, it has not yet been widely documented in major news sources.

In forum threads and social‑media posts, you’ll often see people time‑stamping her prior testimony (for example, “she took the stand at 2:27”) rather than announcing a new, upcoming date.

  • First trial testimony: April 29, 2024.
  • Retrial testimony: began April 29–30, 2025, with further cross‑examination into that week.
  • No widely reported new or upcoming testimony date at this time.
