The BAU is assigned to work on an old case, which was Hotch's first as lead investigator for the BAU, namely that of the Boston Reaper. The case was originally closed ten years ago by Tom Shaunessy, the lead Boston police detective working on the case. When the case officially closed, the killings stopped. With Shaunessy now on his deathbed, he discloses to Hotch the reasons for closing the case. After Shaunessy's death, the killings once again begin. Hotch is taking this case personally as, although he had thought and worked on his own on the case in the intervening years, he feels he could have stopped the Reaper during this time which may have prevented these recent deaths. Beyond the random persons chosen as the murder victims, the one person who may be in danger as a target of the Reaper is George Foyet, the only known person who survived the Reaper's murder attempt ten years earlier. One other person who may provide a symbiotic benefit to the BAU in finding the Reaper this time ... Written by Huggo

Did You Know?


Rossi describes the Reaper as being a Hebephile, which actually means he has an attraction to young girls just going through puberty (11-14). This is incorrect, the Reaper shows himself throughout the show to actually have Ephebophilia, a condition in which adults are attracted to girls from mid to late adolescence (15-19). See more »

Introducing The Boston Reaper...
30 June 2016 | by (United Kingdom) – See all my reviews

As with most shows 'Criminal Minds' has episodes and seasons that are better than others, and to me "Omnivore" is one of the standouts of the fourth season and one of the better episodes of the show as well.

Flaws are very few and they will seem like very small nit-picks. This reviewer does agree about the accents not being great and that there are a couple of suspension-of-disbelief-that-are-not-so-easy-to-swallow moments. However, it serves as a great introduction to the Boston Reaper, perhaps the most notorious serial killer on 'Criminal Minds' (Billy Flynn and Frank Breitkopf are up there though too) and one of the most chilling, and paved the way for one of the show's better on-going story arcs.

"Omnivore" as always has strong production values, with slick and stylish photography, crisp editing, good locations and some of the most effective use of darkness in the show's history, giving an appropriately ominous feel. The music is sparingly used, but utilised when used in a way that's fitting with the mood and not being intrusive, jaunty or pedestrian. It doesn't enhance as such, but it never distracts either. The theme tune still haunts and hypnotises.

The writing is some of the most taut and thought-provoking of the show, this reviewer appreciated that the comedy relief was kept at minimum seeing as it is a dark story and any more would have spoilt it. The story is tightly paced and absorbing, and one of the darkest and grittiest of 'Criminal Minds' up to this point. While not on screen, the murders and are shocking and the build ups to them suspenseful. The ending also had me floored, having seen many episodes on the show where you know who it is quite early on to find out about three quarters of a way in and find out that it's not who you suspected initially was somewhat refreshing and it's executed really well. The beginning also sets things up excellently, with a sense of dread being evoked even when the Reaper is only being talked about.

All the BAU team are written well, with Hotch (who tended in the early series to be in the shadow of more compelling characters like Reid) being more interesting than usual, while the Reaper is every bit the terrifying criminal mastermind. Directing is always solid and never lets the tension, suspense or the group dynamic dip in impact, and the acting from all the regulars and C. Thomas Howell (whose later appearances were even better than this one) is top-drawer.

In conclusion, great episode and one season 4's standouts. Also does a great job introducing a serial killer and foe that's one of the most notorious and formidable. 9/10 Bethany Cox
