LOS ANGELES (AP) _ Darryl Henley's younger brother and two other men have been arrested as an investigation expanded into whether the former Los Angeles Rams cornerback attempted to buy drugs from his jail cell.

Prosecutors said Eric Henley, 26, was arrested Wednesday night in Texas, and twins Ronald and Donald Knight, both 31, were arrested in Chino and Compton, respectively, by U.S. marshals on Thursday.

The trio allegedly conspired with Darryl Henley's girlfriend, Alisa Denmon, 30, and Kym Taylor, 36, to purchase about 55 pounds of cocaine from an undercover agent, authorities said.

U.S. Magistrate Judge R.J. Groh Jr., ordered Ronald Knight held without bail. His brother was released on a $200,000 bond, with the provision that the telephones in his family's home be tapped.

The complaints against the Knights, Denmon, Taylor and the Henley brothers were filed on April 26 under seal, but the seal was lifted Thursday.

Darryl Henley, who is awaiting sentencing for a cocaine trafficking conviction last year allegedly worked from his jail cell to put the undercover agent in touch with his brother, Taylor and Ronald Knight to arrange the drug deal. Henley's initial conviction has been appealed.

Darryl Henley, 29, was named in another criminal complaint earlier this week for allegedly using a cellular phone a jail guard supposedly provided to put together a $1 million heroin deal and to put contracts out on the judge from his cocaine trial and an ex-girlfriend who testified against him.

Henley allegedly offered an undercover agent $100,000 apiece to kill U.S. District Judge Gary Taylor and former Rams cheerleader Tracy Donaho, who was taken into FBI protective custody. She testified against Henley during his cocaine trial.

As of Thursday, Henley had not been charged with the murder-for-hire scheme. But those charges could be added to an indictment a federal grand jury is expected to hand down next week.

Assistant U.S. attorney Marc Harris said in court earlier this week that Darryl Henley used the smuggled cell phone to arrange a $1 million drug transfer from his Orange County home to Atlanta and Memphis.

Darryl Henley, jail guard Rodney Anderson, 29, of Los Angeles, and Jimmy Washington, 49, Henley's alleged Detroit drug connection, face federal drug trafficking charges, authorities said. Henley and Anderson are scheduled to be arraigned June 17 on those charges.

Henley, his uncle and three others were convicted in March 1995 of masterminding a large-scale cocaine operation to ship drugs from his Orange County home.

None of the men has been sentenced. After the trial, allegations of jury tampering and a bribe attempt surfaced. Hearings on whether to hold another trial have been going on for several months.

Earlier this week, Harris said federal agents tape-recorded Henley discussing the heroin deal with an undercover agent as a way to pay for the alleged $100,000 contract hits. Harris also said Anderson knew about the murder plots and was using his position in the jail to find Donaho.

Henley attended UCLA before joining the Rams as a second-round draft choice in 1989.
