SAN BENITO, Texas (AP) — A South Texas business owner says he was surprised to find two envelopes filled with drugs when he went to check his mail.  

KRGV-TV reports (http://bit.ly/1xllJ7N ) Frank Rios in San Benito alerted police Monday after receiving 177 grams of cocaine. He says the packages were marked "return to sender" and listed the name of his business but that he didn't send them.

San Benito Assistant Police Chief Michael Galvan says authorities are searching for whoever tried to mail the cocaine to a vacant house in Memphis, Tennessee. He says the plastic packages on the inside of the mail are being tested for fingerprints.
