IRVINE – A motorcyclist killed in a solo crash Monday night has been identified as a 22-year-old resident of Montclair, authorities said.

Paul Tapalla was pronounced dead at the scene shortly after paramedics and police responded to the crash just after 8 p.m., officials said.

The crash occurred near Main Street and Paseo Westpark, where the motorcyclist appeared to have hit a sign and a tree.

No other vehicles were involved in the crash, said Lt. Julia Engen of the Irvine Police Department.

“It looks like he just lost control,” she said.

What caused Tapalla to lose control of the motorcycle was still under investigation.

The crash is being investigated by the department’s major accident investigation team.
