YOUNGSTOWN — The Youngstown Police Department and the local office of the FBI teamed up to serve search warrants at two homes on the South Side on Friday morning.

The homes are in the 500 block of Cambridge Avenue and 100 block of East Judson Avenue.

The searches involved use of the Mahoning County Crisis Response Team and an FBI SWAT team in order to carry out two searches at the same time, said Capt. Jason Simon, of the detective division of the Youngstown Police Department.

Two people in the Cambridge home were taken to the police department for questioning. No one was inside the house on Judson, Simon said.

At the Cambridge Avenue home, police and others stood by as detectives brought out bag after bag of items and a cardboard box made to carry a long gun.

Because of the “serious nature of the crimes,” the FBI’s local office and the SWAT teams became involved with executing the search warrants, Simon said.

Simon would not say what cases they are investigating, but there have been several in recent months, such as the killings of two people and wounding of four others at two locations on the South Side early Aug. 18.

Persayus Davis-May, 10, was killed while in her home on Samuel Avenue and three adults were shot, but survived, outside of the home.

Within five minutes of that shooting, Michael Callahan, 40, was killed in a pickup truck that was found crashed at South and Palmer avenues. The two locations are 1.3 miles apart.

Police say they believe the incidents are linked.
