A Las Vegas man faces charges of smuggling animal tranquilizers from Mexico intended to help people commit suicide.

In addition, Jeff George Ostfeld is wanted for questioning by Mexican authorities in connection with a death there.

Ostfeld is being held after he was detained at the Progreso International Bridge on Monday near McAllen. Mexican police say he left a hotel without paying and staff found the body of Jennifer Malone of Roseburg, Ore.

The 33-year-old Ostfeld is scheduled for a detention hearing Friday. His court-appointed attorney did not immediately return a call.

U.S. investigators said Ostfeld told them he had flown from Las Vegas to McAllen on May 15 with the intention of buying animal tranquilizers in Mexico. He was detained at the bridge with barbithal and pentobarbital.
