(AP) – Authorities have identified the sixth person killed in a Kansas grain elevator explosion as a 43-year-old grain inspector.

The Saturday blast at the Bartlett Grain Co. elevator in Atchison killed six people and injured two. Five of the dead have already been identified.

The city manager’s office in Atchison identified the sixth person Monday as Darrek Klahr of Wetmore.

He was one of two grain inspectors killed. The other was 34-year-old Travis Keil of Topeka.

Three of the four workers who died were from Atchison. They were 21-year-old Ryan Federinko, 21-year-old Curtis Field, and 20-year-old Chad Roberts. Also killed was 24-year-old John Burke of Denton.

Field, Keil, and Klahr were found Monday after crews were able to get into parts of the building made unstable by the blast.
