PillSudafed E-Coli Cases

The Winquist team has taken on a wide range of high- profile criminal and civil cases. They’ve provided crucial evidence resulting in many criminal convictions including a Sudafed tampering case in which many people were murdered or sickened by cyanide-laced Sudafed. They’ve also provided key investigation on an E-coli poisoning case in which many were sickened by tainted food.


security-01Securities Fraud Cases

Rose and her team also have solved complex securities fraud cases. We provided investigative services on a case involving a short-selling scheme that used the Internet to undermine the value of a pharmaceutical company’s product and stock, by creating the false impression that a new research company was about to bring out a generic version of the legitimate company’s drug.


elders-01Elder Exploitation Cases

Our team also has taken on many elder abuse and financial exploitation cases. One involved a wealthy widow with early dementia who was befriended by a pastor who financially exploited her, including convincing her to write a new will leaving all her money to him. We found crucial evidence showing the pastor’s undue influence on the widow, which allowed the Court to invalidate the new will.


finance-01Financial Exploitation

In another case, Rose and her investigators found evidence showing that a wealthy widower was bilked out of most of his savings by a convicted murderess who trolled Internet dating sites for elderly and financially secure men. This allowed the Court to issue a $2.3 million civil judgment against the woman for financial exploitation of a vulnerable adult, and put her in prison for 5 years.


missing-01Missing Persons

Our investigators are also working on locating the missing body of Mark Stover. Mark was the subject of a 48 Hours Investigation, called The Dog Trainer, The Heiress and The Body Guard.

Rose is currently working on many missing persons cases including the unsolved homicide of Tanya Frazier, a 14 year old girl who was murdered in 1994 and whose body was found in a vacant lot a week later. We are also working on finding the missing young woman, Susan Cox Powell.
