Detroit police are investigating the death of a 42-year-old high-tech executive from California whose body was found near a topless bar.

The body of Benjamin Goldman was discovered Aug. 19 about a block from the Penthouse Club. Police spokesman James Tate says Goldman wasn't immediately identified because there was no wallet.

Tate says Goldman, a marketing executive, was in Detroit on a business trip for Cisco Systems Inc. He lived in Los Gatos, Calif.

No one was in custody Wednesday. Tate says police are interviewing many people.

The San Jose Mercury News says 400 people attended a memorial service in California. Goldman worked at Cisco for 16 years.
