A group of moms known as mombies hosts a Halloween flash mob each year, in which members get zombified and perform to Michael Jackson's Thriller, CBS News reported. The performance has a fundraising purpose, and the network's report says it is intended to raise money for breast cancer.

According to the summary of the CBS News video report, the group has almost doubled in size since 2016. The report also states that preparing for the event takes weeks of rehearsals and that the group stages two different shows. The summary describes the flash mob as having a purpose, which it identifies as raising money for breast cancer.

The summary does not say when the group began performing, although it refers to 2016 as the point from which the group's growth is measured. It also does not give the current number of members, the amount of money raised so far, the locations or dates of the two shows, or the name of any organization that receives the funds.

Tony Dokoupil is credited in the summary as the reporter who has the story. The summary does not include quotes from members of the group or from any organization connected to breast cancer research or support, so the account available for this report relies on the description of the performances and the stated fundraising goal.

No other outlet's coverage of the group was included in the material for this story, so no second account was available to compare or confirm the details in the CBS News summary. Readers seeking the full account of the performances, the group's history, or its fundraising totals would need to consult the video report itself, which the summary describes only in brief.
