A grand jury called Golden Nugget officials.

Summoned before a federal grand jury in Newark, N.J., are Chairman Stephen Wynn and casino executive D. Boone Wayson as well as an unidentified marketing employee of the firm’s Atlantic City, N.J., casino. Alfred Luciani, a company attorney, said the probe involves suspected money laundering by a baccarat customer who deposited $1.1 million in small bills with the casino in 1982, lost $300,000 gambling and was given the balance in large bills. Separately, Golden Nugget announced that it will build a $115-million high-rise tower at its Las Vegas gambling hall.
