THREE ARRESTED IN CONNECTION WITH death of employee crushed by a steamroller 

SAN FRANCISCO – Today, District Attorney George Gascón announced that Ramiro Pena Pena, age 48 of Dublin; Michael Sommer, age 41 of Pacifica; Manuel Silao, age 59 of Richmond; and L C General Engineering and Construction, Inc., were arrested yesterday in connection with the workplace death of an employee. The victim was run over by a steamroller that was operated by a fellow employee. The four co-defendants are being charged with one felony count of involuntary manslaughter and three felony violations of the labor code.

“When businesses ignore regulations designed to create safe workplaces, they put their employees and the community at risk,” said District Attorney George Gascón. “The stakes are high, and the volume of construction underway in San Francisco requires these companies to take the precautions necessary to mitigate the risk of injury.”

According to court documents, Mr. Sommer, the President of L C General Engineering and Construction, Inc.; Mr. Silao, a Project Manager; and Mr. Pena, a Foreman, all contributed to permitting a worker, who was not qualified, to operate a heavy roller at the worksite.  That employee had not previously operated a steamroller or received the proper training to do so, and was operating the machinery at the direction of his employer. The operator lost control of the roller and ran over the victim near the intersection of Vincente Street and 18th Avenue.

Mr. Pena’s arraignment will occur at 1:30 PM today in Dept. 12.; Mr. Sommer’s will occur on August 30, 2018; Mr. Silao’s on September 4, 2018; and L C General Engineering and Construction, Inc.’s, on September 24, 2018.  These arrest and charges are the result of an excellent investigation primarily conducted by the California Division of Occupational Safety and Health. Special recognition goes to San Francisco District Attorney Senior Inspector Brian Arnold for his assistance with the investigation. Assistant District Attorney Gregory Alker is prosecuting the case.
