Paula Beverly Davis

Dr. No is the nickname given to a suspected American serial killer thought to be responsible for the murders of at least nine women and girls in Ohio, between 1981 and 1990.

As victims, Dr. No primarily chose prostitutes working in parking lots and truck stops located alongside Interstate 71.

The killings began in 1981, when the body of a young woman was found in Miami County, Ohio on April 24.

After a forensic examination, it was determined that the victim died from strangulation, having received a head injury beforehand.

At the time of her discovery, no personal belongings or documents were found, making her identification difficult.

She was well-groomed, and there was no evidence of sexual assault; investigators did not characterize her as a sex worker.

She was nicknamed "Buckskin Girl", from a tasseled buckskin poncho she was wearing.

The next victim was 25-year-old Marcia Matthews, who was found, beaten but barely alive, on June 16, 1985, by a trucker one mile away from the Union 76 truck stop.

She died two and a half days later from a traumatic brain injury, sustained after a beating with a blunt object.

There are suspicions that he committed three similar killings in New York, Illinois and Pennsylvania, between 1986 and 1988.

Some of the victims were sex workers at the Union 76 truck stop in Austintown, east of Akron and west of Youngstown, which is the largest in Ohio, leading the investigators to suspect that the killer was a truck driver.

Most victims were found without underwear and shoes.

On July 20, 1986, the body of 23-year-old sex worker Shirley Dean Taylor was discovered, who was also beaten and strangled to death.

Before her disappearance, she was seen at the Union 76 truck stop, where, according to witness reports, she went to meet a regular client nicknamed "Dr. No", whose identity was never established.

Her body was discovered a few miles from the place of her disappearance, with her underwear and shoes missing.

In December 1986, 18-year-old sex worker April Barnett also went missing from the Union 76 truck stop, with her body found only a few days later 70 miles from Austintown.

As with previous cases, the victim was beaten and strangled to death, with some of her clothes missing as well.

A few days later, 28-year-old sex worker Jill Allen was found murdered in Illinois, near Interstate 70.

Despite the fact that she had been found in another state, she was deemed a victim of the same killer due to the modus operandi.

Allen had also been beaten and asphyxiated, with strangulation marks found on her neck.

Her shoes, bra, and underwear were never found.

The next victim was 27-year-old Anne-Marie Patterson, who went missing on February 7, 1987, from the Union 76 Austintown.

Her semi-decomposed body was found 40 days later, 250 miles away from Austintown, near Cincinnati.

A week before the disappearance, Patterson had been arrested by police.

At the police station, she gave information about a murder suspect and described his car.

During the investigation, law enforcement agencies discovered that Patterson had made an appointment via CB radio with the client, nicknamed "Dr. No", whom she characterized extremely negatively, and then disappeared.

From this, the police and later the media used the nickname for the unidentified criminal.

On August 10, 1987, another victim's body was found in Englewood.

The victim's jeans and underwear were at her ankles, while the upper parts of the clothes were missing.

According to the nature of grass depressions and tire tracks located at the scene, forensic experts determined that the killer threw the victim's corpse out of his car.

An autopsy revealed that the victim was a young woman, aged 20–25, and had died from strangulation.

On November 22, 1987, the body of 19-year-old Lamonica Cole was discovered at a truck stop in Breezewood, Pennsylvania.

Despite the fact that the truck stop was located on another interstate, Cole was included as a potential victim because she had died from strangulation, was a native of Ohio and some of her things had been recovered, while others not.

During the investigation, Lamonica's pimp, 24-year-old Derrick Mims, told police that the alleged killer with whom Cole left on the day of her disappearance was traveling in a blue Semi-trailer truck with white stripes.

31-year-old Terri Roark was murdered March 29, 1988 in New York, her body found on one of the bridges passing through the Mohawk River.

The medical examiner found that the woman died from a traumatic brain injury that occurred during a beating with a blunt object several hours before the discovery of her body.

Although she was included on the task force relating to the murders (formed in 1991), additional theories exist suggesting a drug dealer's retaliation, an unknown woman last seen in her company, or an unrelated serial killer.

Despite the abundance of tattoos on her body, as well as jewelry the offender had not stolen, she remained unidentified until 2010.

The victim was identified as Paula Beverly Davis, 21, after relatives recognized her tattoos pictured from her listing in the National Missing and Unidentified Persons System.

In 2018, the victim was finally identified as Marcia King.
