Delivery, fail.

Expecting to find a box of tools he had ordered, one north Texas man found 30 pounds of marijuana. Street value: $10,500.

"I personally have not seen that much," Denton police officer Ryan Grelle said. "This is the first time I've seen roughly 30 pounds of marijuana."

Investigators said the recipient immediately drove the drugs to Denton police headquarters.

"The man came up and said something like, 'I just want to talk to an officer and don't want to talk to anyone else until I talk to an officer," Grelle said.

According to police, the box was sent from Pharr in south Texas and made its way through Austin, Mesquite, Dallas and then Denton.

"UPS tried to deliver to the Dallas address, but the person sending it put down a street that doesn't exist," Grelle said.

Detectives said they believe UPS diverted the package to a street with a similar name in Denton.

UPS spokeswoman Susan Rosenberg said UPS works with law enforcement on drug cases. She said the shipping company scans some of its shipments but couldn't divulge what technology is used because of security reasons.

Denton police said they've turned over information on the shipping address to narcotics officers.

The man who turned the marijuana in does not face criminal charges.
