HOUSTON (AP) — A federal judge has told jurors to continue deliberating at Texas tycoon R. Allen Stanford’s fraud trial after they indicated they’re deadlocked on at least some of the 14 charges against him.

Stanford is accused of bilking investors out of $7 billion in a massive Ponzi scheme.

U.S. District Judge David Hittner on Monday gave jurors in Houston an order meant to prod juries toward a unanimous verdict. A short time later, the jury ended work for the day. Deliberations are to resume Tuesday.

The jury has been deliberating since last Wednesday.

Defense attorneys say Stanford made money for investors who bought certificates of deposit from his Caribbean bank.

Prosecutors counter Stanford spent their money on failed businesses and a lavish lifestyle.
