David W.C. Clark, 38, a lawyer convicted in the insider trading scandal involving a Wall Street Journal columnist, died Jan. 16 at his mother's home in Fort Lauderdale, Fla.

A spokesman for the Broward County Medical Examiner's office attributed his death to chronic alcoholism.

Mr. Clark was convicted in November of 16 counts of fraud, tax evasion and perjury and could have been sentenced to 75 years in prison. He was free on bail pending sentencing Jan. 22 in U.S. District Court in New York City.

The conviction stemmed from stock trading by Mr. Clark while he was a lawyer in New York. He was charged with embezzling $3.7 million from clients to underwrite his trading.

The indictment also said he failed to report his trading profits and twice lied to Securities and Exchange Commission investigators.

He and Peter N. Brant, a former stockbroker at Kidder, Peabody & Co., were charged with paying The Wall Street Journal's R. Foster Winans to tell them what stocks he planned to discuss in his influential "Heard on the Street" columns. Winans was convicted two years ago on mail and wire fraud charges, and his conviction was recently upheld by the U.S. Supreme Court.

Mr. Clark was a native of Kansas City, Kan. He was a 1970 graduate of Columbia University and received a law degree from Fordham University in 1974.

Survivors include his mother, Margaret Conger Clark, two sons, and two brothers.
