MIAMI (AP) _ Jurors went a second day Wednesday without rendering a verdict in the trial of Miami Dolphins receiver Tony Martin, charged with five federal counts of money-laundering.

The panel of eight women and four men discussed the case, now in its fourth week, for slightly more than six hours Wednesday. They now have deliberated for about 12 hours over two days.

U.S. District Judge K. Michael Moore instructed the jury to return at 8:30 a.m. Thursday.

Martin is being tried alongside Rickey Brownlee, who spent seven years in prison for two 1980s drug convictions, in a case largely focusing on Brownlee's alleged narcotics activities from 1994 to 1997.

The Pro Bowl receiver is charged with four counts of laundering drug profits and one of conspiracy to hide drug money. He faces a prison term of 3-5 years if convicted.

Martin spent the day huddled with his lawyers or with his parents, girlfriend and supporters in the waiting area outside the courtroom. At one point he dozed in an overstuffed blue chair.

After lawyers passed along word that the jury was going home, Martin signed an autograph for 15-year-old Wilson Louis of Miami. Underneath his signature, Martin wrote: ``Good luck in life.''

``He looks innocent to me,'' said the teen-ager, who said he came to the courthouse because he wants to become a reporter. ``This is just wasting his time for nothing.''

Martin, 33, is accused of leasing three cars in his name on behalf of Brownlee, who repaid him with cash. He also is accused of taking $100,000 in cash to reimburse a check written to Brownlee's first lawyer, though he later stopped payment on the check and returned the money.

At issue is whether Martin, who has known Brownlee since childhood and calls him his uncle, knowingly accepted drug money.
