A Pennsylvania man was charged Tuesday for the murders of two Coatesville women, and the killing of an unborn child in connection with a Sunday night incident that involved a carjacking, a high-speed police chase, and multiple gunshots.
23-year-old Mamadou Kallie was arrested for the murders of 20-year-old Tiara Rodriguez-Diaz and 21-year-old Kimberly Ortiz-Zayas, and the killing of Ortiz-Zayas’ unborn child on May 29, in Valley Township.
Kallie is charged with two counts of first-degree murder, murder of an unborn child, carjacking, fleeing and eluding, endangering the welfare of a child, and related charges. Kallie is being held without bail due to the nature of the charges at Chester County Prison.
According to the Chester County District Attorney’s office, it all took place on May 29 at 9:21 p.m., when Coatesville Police responded to a domestic dispute in the 300-block of Mount Pleasant Street between Kallie and Rodriguez-Diaz while they were visiting friends.
Rodriguez-Diaz, who was inside a Toyota Corolla with their 22-month-old child in the back seat, told officers that everything was fine. Kallie, who was wearing a black shirt and a black baseball cap with a design on the front, became agitated when police questioned the victim but walked away from Rodriguez-Diaz’s car and got into a black Ford Edge.
After speaking with the victim and Kallie, Rodriguez-Diaz drove off with the child in the back, and police cleared the scene.
Thirty minutes later, Valley Township Police responded to an accident, and the report of shots fired in the 300 block of East Glencrest Road in Valley Township. A witness told police she heard nine shots fired, and another witness reported seeing a black SUV flee the scene.
Police found Rodriguez-Diaz in the driver’s seat of a Toyota Corolla with multiple gunshot wounds. She was taken to Paoli Hospital, where she was pronounced dead shortly after arrival.
Investigators discovered a trail of blood from the car’s front passenger door to Ortiz-Zayas lying on the side of the road. She was pronounced dead at the scene. Police later learned that she was five months pregnant. A black baseball cap with a patch containing a wolf and the words “lone wolf” was observed next to the body of the female.
Fired cartridge casings were located inside and outside the car, and a cellphone covered in blood was found on the center console. Investigators observed a dent in the Toyota Corolla and a tire mark transfer on the driver’s side rear door. The child was not found at the scene.
At 10:45 p.m., West Chester Police responded to the report of a carjacking at Route 162 and Telegraph Road in East Bradford Township. A victim, known to Kallie, reported that his black Infiniti was stolen at gunpoint by Kallie. He stated that while he was detailing his car on the 100 block of Pennsylvania Avenue on May 29, Kallie pulled up in a black Ford Edge, jumped into the victim’s car, and ordered him to drive and to stay on back roads. He told him to drive to Philadelphia and asked him for a change of clothes. Kallie later pointed a black handgun at his head while he was driving and ordered him out of the car in East Bradford Township.
The victim flagged down a passing motorist and called the police.
After a police pursuit involving multiple police units, where they attempted to stop the Infiniti using sirens, lights, and stop sticks, Kallie was stopped in Caln Township. at 11:04 p.m.
Kallie exited the car holding a gun to himself. Police successfully negotiated a peaceful surrender, and he was taken into custody at 11:41 p.m.
Police recovered a Taurus G2C 9mm pistol, which contained a live round in the chamber and a live round in the magazine. Detectives saw red stains on the defendant’s shirt consistent with blood.
Coatesville Police later located the black Ford Edge parked on Star Alley, near the 100 block of Pennsylvania Avenue. Police observed damage on the front passenger side of the car. A car part with Ford markings that was missing from the Ford Edge was found under the passenger side of the Toyota Corolla where the victims were shot.
The 22-month-old child of the defendant and Rodriguez-Diaz was later found uninjured in Coatesville with relatives of the defendant. Authorities believe Kallie removed the child from the car after shooting the two women.
“The senseless and tragic murders of two women and an unborn child are outrageous,” said Chester County District Attorney Deb Ryan. “Domestic violence continues to plague our communities and homes, and its ripple effect has life-altering consequences for too many people. We will do everything in our power to hold Mamadou Kallie accountable for these premeditated, intentional, and cold-blooded murders.”
Said Valley Township Police Chief Glenn Eckman: “Valley Township experienced a horrific double murder on a holiday weekend when family and friends were supposed to enjoy summer’s unofficial start. Instead, two young women and an unborn child are dead. It was a brutal scene for law enforcement to process, but I thank all our partners for their collaboration in finding and arresting the defendant.”
Chester County Detectives and Valley Township Police are investigating. DDA Erin O’Brien is the assigned prosecutor.
