A 32-year-old heavy equipment operator was badly injured Monday morning when a truck, driven by an elderly man, pinned him against a trailer on which he was loading an excavator near Duson, officials said.

Jonathan Strandridge is in critical condition and was undergoing surgery at a Lafayette hospital, Lafayette Parish Sheriff’s Capt. Kip Judice said in a news release.

Judice said sheriff’s deputies responded to the call at 8:29 a.m.

Strandridge, who works for Gulfgate Contractors, had completed a trenching job near the intersection of Landry and South Fieldspan roads. Strandridge was in the roadway and working to get the excavator onto a trailer when 90-year-old Ralph Hogan turned east onto Landry Road from Fieldspan, Judice said in a release.

“Hogan stated (that) as he turned onto Landry Road the sun blinded him temporarily and he struck Strandridge, who was standing at the back of the trailer securing the ramps, pinning Strandridge between the trailer and Hogan’s truck,” Judice said.

Toxicology samples are pending in a case that remains under investigation, Judice said.

Hogan was not injured and was not issued a citation.
