A man was struck and killed by a Metrolink train in Mission Viejo on Saturday after lying across the train tracks, authorities said.

The apparent suicide comes days after another man, 35-year-old Brandon Reis of Brea, was killed after he stood in front of a train in Fullerton on Wednesday.

The victim Saturday, whose name was not immediately released, was lying on the tracks near El Paseo at about 12 p.m. when he was hit by a southbound train, said Orange County Sheriff’s Lt. Jerry Carlsen.

The conductor initially thought he had hit debris but stopped in Oceanside after he was alerted to the incident when another train passed the scene, Carlsen said.

He checked the undercarriage and found a broken hose and part of the victim’s shirt, Carlsen said.

Northbound and southbound trains were delayed for about an hour as officials investigated.
