The Madison Police Department announced Friday it has located a vehicle suspected to have been involved in the Sunday morning hit-and-run accident that killed a Madison woman.

No arrests have been made, but a person of interest has been identified in the death of 46-year-old Tina Harrod, Chief Dan Thurston said.

No other information about the case was being released Friday.

Harrod was walking in the 2300 block of Wilson Avenue toward her nearby home when she was struck by a passing vehicle that left the scene, police said.

Passersby found Harrod lying in the roadway at about 3:45 a.m.

She was unresponsive when police arrived.

Harrod was a certified optometry assistant at Madison Vision Clinic and later with Taustine Eye Center.

Among her survivors is a son, Skyler, stationed at Yokota Air Base, Japan.

Harrod's funeral was Friday with burial in Vevay Cemetery.
