A red and white Piper Arrow, two passenger single engine aircraft, carrying 27-year-old Kayla Rodriguez and 43-year-old Justin Winfrey, disappeared off radar at 9:21 p.m. Thursday.

“Their plane descended below radar between Wheeler and Rockport off the coast,” Kayla’s father, Larry Rodriguez told us.

Rodriguez, a delivery nurse in San Francisco, and Winfrey, a businessman, were supposed to be going to a “haunted house somewhere up north,” according to a informational piece put out by the family. But “no flight plan was filed–so officials only have “radar” or eye witnesses to go off of when trying to locate the plane.”

Rodriguez’s father told us, “We are trying to get in touch with fishermen and local charters. Trying to get as many people as possible to see this.”

“Please call local officials if you have seen this plane flying low between Fort [Bragg] or Eureka,” the missing persons poster says.

Coast Guard Petty Officer Bacon offered slightly contradictory information. Last night, he said that the “aircraft dropped contact approximately 1916 Pacific Standard Time” which is 8:16 p.m. Pacific Daylight Time. This is about an hour earlier than the time period her father understood the plane dropped off the radar.

He said “Once we were notified, C27 fixed wing aircraft…did search patterns over the area…One of our helicopters did a low fly over the area…We also contacted vessel’s in the vicinity [but] they haven’t heard anything.”

Rodriguez and Winfrey were last physically seen topping off the plane’s fuel tank at Gnoss Field Airport in Novato at 5:30 p.m.

Please call your local law enforcement if you have any information.
