Coatesville Man Held For Trial In Memorial Day Weekend Slayings

WEST CHESTER, PA —A Coatesville man was held for trial Tuesday on charges of killing two women and an unborn child and carjacking another victim on Memorial Day weekend.

Mamadou Kallie, 23, did not testify in his preliminary hearing before District Judge Nancy Gill in the Chester County Justice Center.

Kallie is accused of fatally shooting Tiara Rodriguez-Diaz, 21, the mother of his 22-month-old son, and her friend, Kimberly Ortiz-Zayas, 20, who was five months pregnant. Both victims resided in Coatesville.

The boy was uninjured and is reportedly staying in Coatesville with relatives.

Kallie is accused of the two slayings and carjacking of another person during a two-hour and 20 minute period that ended in his arrest on May 29.

The events covered four Chester County municipalities.

According to court records:

• At 9:22 p.m., Coatesville police officers responded to a call involving a domestic dispute in the 300 block of Mount Pleasant Street.

Rodriguez-Diaz was in her Red Toyota with her son in the backseat. She told police everything was fine. Kallie became agitated, but walked away and got in his black Ford.

• At 9:52 p.m., Valley Township police responded to an accident and reports of nine shots being fired in the 300 block of East Glencrest Road. Rodriguez-Diaz was taken to Paoli Hospital, where she was pronounced dead.

Police followed a trail of blood from the car to the side of the road where they found Ortiz-Zayas, who was five months pregnant. She was pronounced dead at the scene.

• At 10: 45 p.m., West Chester police responded to a carjacking at Route 162 and Telegraph Road, East Bradford Township.

An acquaintance of Kallie reported he was held at gunpoint, and his car had been stolen by the suspect. After a police pursuit, the suspect was stopped in Caln Township.

• At 11:04 p.m., the suspect exited the car holding a gun to himself.
• At 11:41 p.m., police negotiated the suspect's peaceful surrender.

Police recovered the firearm the suspect was holding, which contained a live round in the chamber and a live round in the magazine.

Kallie is in Chester County Prison without bail on charges of first-degree murder, murder of an unborn child, carjacking, endangering the welfare of a child and related charges

He is scheduled for arraignment later this month in the Chester County Justice Center.
