SAN DIEGO — A bicyclist killed over the weekend in a collision on a Black Mountain Ranch roadway was a top-level executive for Rady Children’s Hospital, officials reported Monday.

Roger Roux, 64, was riding in a bike lane in the 14200 block of Camino del Sur, near State Route 56, when a car struck him shortly before 3:30 p.m. Sunday, according to police and the county Medical Examiner’s Office.

Medics took him to Scripps Memorial Hospital La Jolla, where he was pronounced dead.

The motorist, a 40-year-old woman whose name was withheld, was not immediately cited or arrested. An investigation is ongoing, SDPD spokesman Humberto Hernandez said.

Roux was a senior vice president and chief financial officer of the Serra Mesa-area medical center for children, responsible for all facets of the institution’s financial operations, including accounting, budgeting and patient financial services, Rady spokesman Ben Metcalf said.

During his 12-year tenure with the hospital, Roux, a Boston native, “helped bring Rady Children’s to its strongest financial performance in its 60- year history,” according to Metcalf.

“His contributions to Rady Children’s and the San Diego community are simply too many to enumerate,” the spokesman said. “Roger was a dedicated, trusted and collegial member of the Rady Children’s family and will be missed dearly.”

Roux is survived by his wife, Diane, son, Matthew, and grandchildren, Emerson and Xavier.
