Two people were killed and three others were injured in two related shootings in Carrollton, Texas, on Tuesday morning.

Police arrested Seung Han Ho, 69, who is accused of carrying out both attacks after a business dispute turned violent.

The first shooting happened inside the Gwang Jang Korean Market, where four people were shot and one died at the scene.

The second occurred later in an apartment in the city’s Koreatown area, where another man was found dead, with investigators linking both incidents to the same suspect, CBS News has reported.

Authorities say Ho confessed and said the violence was driven by financial disagreements, prompting a large police response and nearby business closures.
