LOCKPORT TOWNSHIP, Mich. (AP) — Authorities say three people were killed in a southwestern Michigan crash in which a car struck a tree and the vehicle split in half.

St. Joseph County sheriff’s officials say 23-year-old Damian Long, 29-year-old Christina Slusher and 20-year-old Kassidy Robinette died in the Saturday morning crash in Lockport Township. Investigators say Long, who was driving, lost control on a turn and the car hit a tree.

Police say speed likely played a role but they haven’t determined if drugs or alcohol were factors.
