This describes all the disturbing details regarding the recent meat scandal in Los Angels prior to the store being sold. The article clearly indicates that perhaps the greatest problem is the alleged betrayal of the community by someone who was highly respected and trusted for years as  well as the failure of the kashrus supervision to aggressively follow up on rumors of wrong doing.
Jewish Journal   
 On Thursday, March 7, at 6:10 a.m., a van and an SUV sit in adjacent 
parking spaces, in the lot of a McDonald’s near the junction of the 101 
and the 405 freeways, their rear lift-gates open. 
 
Mike Engelman, the driver of the SUV, with the help of the driver of 
the van, loads something into the back of the SUV. Then Engelman, who 
owns Doheny Glatt Kosher Meat Market, one of Los Angeles’ largest 
distributors of kosher animal products, drives off, headed to 
Pico-Robertson to open his shop. 
Almost exactly one hour later, in the parking lot behind Doheny Meats, 
the mashgiach (rabbinic overseer) from the Rabbinical Council of 
California (RCC), who had unlocked the doors to the store and the 
distribution center just 10 minutes earlier, is nowhere in sight.  
Engelman signals to an employee to unload the SUV. The employee takes 
out eight boxes, hundreds of pounds of unidentified meat or poultry, and
 wheels them into the store through its rear door.
This entire sequence was captured on video by a private investigator, 
and on Sunday afternoon, March 24, Rabbi Meyer H. May, president of the 
RCC, watched the video in horror. What he saw wasn’t just Engelman 
undermining the supervision of his agency; he also saw the rabbinic 
supervisor, who is never supposed to leave the premises, break with RCC 
protocol. [...]
The once-beloved butcher
Mike Engelman used to be known as the butcher with the highest-quality 
kosher meat and poultry in Pico-Robertson. His store is located within a
 10-minute walk of four major kosher markets, and Doheny Meats serves as
 both a supplier and a stand-alone shop that carries animal products — 
including rare meats like bison and elk — and little else. The  
employees’ white hats and aprons, the sparkling white display case, the 
thick white paper in which cuts of meat are wrapped — the entire 
shopping experience there feels like a throwback to a time when most 
people knew their butchers by name.
Which is what it was: Doheny has been around for more than 50 years, 
and Engelman made good service a selling point. Whole chickens bought 
from Doheny, for instance, were passed through an open flame to singe 
any stray feathers off of the skin. Doheny delivered its products 
locally, but also drew customers from other cities. At one point in the 
early 1990s, Doheny was making monthly deliveries to a synagogue in the 
South Bay and, according to the store’s Web site, which, as of April 1, 
had been taken down, Doheny had scheduled a delivery to a buying club in
 San Diego in March and was set to make similar shipments to the San 
Francisco Bay Area as well.
It was Engelman’s success on the distribution side — selling to 
caterers, markets, restaurants and hotels, including luxury venues like 
the Beverly Hilton in Beverly Hills, which made up the majority of the 
volume of his business — that raised suspicions. [...]
