Investigators returned to the scene Friday of a crash that killed a motorcyclist in Reading earlier this week.

Members of the Berks County district attorney's forensics investigation unit took detailed measurements of the scene in the 1000 block of Penn Street.

Daniel Felix was driving an off-road motorcycle erratically when officers tried to stop him Sunday afternoon, police said.

Felix, 29, of Reading, kept going until the bike struck a vehicle and a curb near 11th and Penn streets. He died at the scene.

Police Chief Bill Heim told 69 News that Friday's work was a routine part of the ongoing investigation.

He also said Monday that the city has seen an increased use of the illegal bikes on the streets over the past few years.
