Wesley Eugene Baker (March 26, 1958 – December 5, 2005) was an American convicted murderer executed by the U.S. state of Maryland. He was sentenced to death for the June 6, 1991, robbery and murder of Jane Frances Tyson, a mother and grandmother, in front of two of her grandchildren in Catonsville. Baker was the last person to be executed in Maryland before capital punishment was abolished in 2013.

Baker was born to an underage rape victim and suffered physical and sexual abuse during his childhood by his mother, stepfather and two teenage girls. At age 15, he fathered a child with a 28-year-old heroin user while himself suffering from alcohol and heroin addiction.

Baker had several prior convictions. His first was for unauthorized use of a motor vehicle at 16 years old, for which he received 3 years in prison. In 1978, Baker was convicted of armed robbery and sentenced to 15 years in prison. Released in 1987, he was arrested again for drug and weapons-related offenses two years later. Baker was paroled in September 1990 and committed the murder that sent him to death row less than nine months later. He was still on parole at the time of the murder.

Wesley Baker approached Jane Tyson, 49, on June 6, 1991, in the parking lot of Catonsville's Westview Mall as she got into her car with her grandchildren, a 6-year-old boy and a 4-year-old girl, after shoe shopping. He placed a gun to her ear and demanded her purse and then, without warning, fired the gun, killing her instantly. Baker fled to where his accomplice was waiting with a Chevrolet Blazer. A member of the public spotted the two fleeing in a car. He noted the license number and called the police, who apprehended Wesley Baker and Gregory Lawrence a short time later.

Baker was convicted by a jury in the Circuit Court for Harford County on October 26, 1992, of first degree murder, robbery with a deadly weapon, and use of a handgun in the commission of a felony. The jury condemned him to death after being informed of Baker's prior convictions and the fact that he was on parole at the time of the murder. Baker also received a 40-year sentence for the other two charges. The conviction and sentence were upheld by the Maryland Court of Appeals. Lawrence was convicted of the same charges a year earlier and received life in prison plus 33 years.

The court decided to uphold Baker's conviction, but there were doubts raised that Baker was the shooter. The 6-year-old boy said that the shooter ran to the driver's side of the car, while a member of the public said that Baker was sitting in the passenger seat. Tyson's blood was found on Baker, but police never tested the clothing of Lawrence. Fingerprints from Baker's right hand were found on Tyson's car, but Baker is right-handed, which lead the United States Court of Appeals for the Fourth Circuit to note in 2000:

…one must wonder how it was possible for [Baker] to hold the gun to Tyson's head and leave his fingerprints on the [car], especially in light of the fact that the incident took only a matter of moments.

The court also wrote that the evidence that Baker was the shooter "was not overwhelming."
