Glenn C. Hoppert, 58, a retired commander of the D.C. police criminal investigations division, died June 17 at a hospice in Branford, Conn. He had colon cancer.

Cmdr. Hoppert began his police career in the late 1960s after serving in the Army in the Vietnam War. From 1986 to 1992, he was president of the Metropolitan Police Officials Association, which represents the D.C. department's ranking officers.

He became commander of the criminal investigations division in 1996. He was often described as a friend and golfing partner of then-D.C. Police Chief Larry D. Soulsby.

Soulsby resigned in 1997 amid a scandal involving reduced rent for an apartment he shared with a roommate, Lt. Jeffery S. Stowe. Stowe, who served under Cmdr. Hoppert, was imprisoned for theft, wire fraud and extortion.

In the aftermath, an interim police chief demoted Cmdr. Hoppert to inspector and transferred him to the labor relations division. However, he retired in 1998 at his old rank of commander.

Cmdr. Hoppert, who was never charged in the scandals, testified before the D.C. Council Judiciary Committee in December 1997 about rampant "corruption, coverups and mismanagement" he witnessed in the department.

Glenn Carroll Hoppert was born in Baltimore, where his father was a firefighter. After graduating from Baltimore's City College, he served in the Army's 101st Airborne Division in the Vietnam War. His decorations included the Silver Star and the Bronze Star.

The Silver Star citation says that on Jan. 13, 1967, near Kontum, he was a member of the "point lead element" as his company moved toward high ground. Detecting an enemy ambush, he charged and killed an enemy soldier, causing other communist fighters to run away. Soon after, his company became pinned down by enemy fire. He charged through the gunfire and pitched a grenade, killing four of the enemy and causing the others to flee.

"Specialist Hoppert's valorous actions resulted in the destruction of two enemy positions, five enemy killed and the saving of several American lives," the citation says.

He was a former president of the 101st Airborne Division Association's national capital area chapter.

He moved to Shelton, Conn., from Columbia in 2000. In retirement, he played at local golf tournaments on the Eastern Shore and in Connecticut.

His marriage to Joan Lowenthal Hoppert ended in divorce. A son from that marriage, Steven Hoppert, died in 2003.

Survivors include his wife of 12 years, Donna Rothert Hoppert of Shelton, Conn.; a son from the first marriage, Darren Hoppert of Laurel; two stepsons, Adam Farver of West Palm Beach, Fla., and Andrew Farver of New York; a brother, Charles Hoppert of Cumberland, Md.; and two sisters, Virginia Spurrier of Sarasota, Fla., and Kathryn Haas of Yorktown, Va.
