Tammy Zywicki Update: Solved! A 30 Years Old Case

On Thursday, a long-haul trucker from Iowa was being questioned by authorities from numerous states regarding his possible involvement in other unsolved homicides.

The police in Waterloo detained 58-year-old Clark Perry Baldwin on suspicion that he was responsible for the deaths of three women whose remains were found in Wyoming and Tennessee. 

According to court filings, a Texas woman was allegedly r*ped and choked by him in 1991.

According to Iowa Division of Criminal Investigation special agent Mike Krapfl, investigators are “looking at any connections” Baldwin may have to cold cases from that era. 

He claimed that other organizations were watching Baldwin because of his frequent travels.

Who are Baldwin’s alleged victims?

Tammy Zywicki was thrilled to drive from Evanston to Grinnell College in Iowa in August 1992. 

The 21-year-old was on her way to college from New Jersey but had to detour to Evanston to drop off her brother at NU.

Unfortunately, Tammy didn’t make it to her college.

Tammy Zywicki, a 21-year-old college student from Iowa, went missing in 1992 after her automobile broke down on an Illinois highway.

A man in a semitrailer was spotted following close behind her car.

The body of Zywicki was located in a remote area of Missouri.

Another case is that of 22-year-old truck stop convenience shop employee Rhonda Knutson, who was murdered while on the job in 1992. 

Sketches of two individuals, one of whom was a truck driver, who was seen at the store have been published by investigators.

Baldwin was a resident of the town of Nashua, Iowa.

He is accused of killing two women in Wyoming in 1992, and their remains were discovered around 400 miles apart. 

The ladies were never formally identified by investigators and were given the codenames “Bitter Creek Betty” and “I-90 Jane Doe.” 

Baldwin faces two counts of murder concerning the 1991 deaths of Pamela McCall, 32, a pregnant woman from Topping, Virginia, and her unborn child in Tennessee.

Tammy Zywicki update

The murder of 21-year-old Tammy Zywicki is similar in many ways to the most infamous “cold cases.”

After a cold case investigator submitted evidence to a crime lab in Tennessee last year, they created a DNA profile of the culprit in McCall’s murder. 

The profile was checked against a national database and found to match one created years earlier that linked the two deaths in Wyoming.

According to court filings, investigators focused on Baldwin after finding the DNA of a relative of the suspect’s profile in commercial genealogy databases. 

An FBI undercover operation in Waterloo last month yielded positive results after taking DNA samples from Baldwin’s garbage and a Walmart shopping cart he had used.

DA Brent Cooper of Tennessee said they did a great job “bringing this serial killer to justice.”

“I’m also thrilled to give Rose McCall’s mother a chance to see justice for the murders of her daughter and granddaughter,” he said. 

The caller said, “At least I have a grave to visit; some moms don’t even know that,” referring to the speaker’s mother.

The investigation strengthened when a woman made a similar claim of violence against Baldwin.

Tammy Zywicki update & Baldwin’s other crimes

Baldwin is accused of s*xually assaulting a female hitchhiker from Kansas at gunpoint in Wheeler County, Texas, in 1991.

The 21-year-old lady claimed to police that Baldwin tried to strangle her to death, hit her in the head, and shackled her wrists and lips.

He confessed to the alleged assault but the police let him go while the grand jury conducted its investigation. In the end, he avoided prosecution.

Baldwin, a former truck driver for Marten Transport, has lived in Nashua, Iowa, and Springfield, Missouri.

His link to an Iowa murder case that the police solved in 1992 was another proof of his involvement.

Baldwin’s ex-wife allegedly told police that he had boasted about “killing a girl out west by strangulation and throwing her out of his truck,” according to court filings.

Moreover, Baldwin’s Springfield, Missouri, residence was raided by the Secret Service in 1997 when they discovered he was using a computer to produce counterfeit U.S. cash. 

He and his two female accomplices were all indicted on counts of counterfeiting.

Baldwin served 18 months of his sentence after which the police released him in 1999.

Jazz Baldwin, 32, of New Hampton, Iowa, was taken aback by the allegations after claiming she knew for two years that Baldwin was her father thanks to a DNA test kit he bought. 

Since then, she claimed, the two had been in constant Facebook communication.

She commented on Facebook, “I heard rumors about his ‘possible crimes,’ but I always thought they were bogus.”

We did not believe that murder was one of the things he had committed and gotten away with.

Tammy Zywicki update is a significant milestone in the conviction of her criminal.
