Authorities said 51-year-old Enrique Saldana called 911 yesterday and said he was at the beach with his wife when she collapsed and stopped breathing.
Police said late yesterday that 43-year-old Jeanette Magras Saldana had bruises all over her body and that it appeared she had died hours before the emergency call was made.
An autopsy will determine the exact cause of death, authorities said.
Saldana is being held on USD 500,000 bond. It was not immediately clear if he had an attorney.
They also were accused of demanding USD 10,000 from the person who rented the car in exchange for not turning in the substance. Authorities say the person paid half the amount and the officers returned all items except the substance.
