John ``Jack'' Maple

NEW YORK (AP) _ John ``Jack'' Maple, a former deputy police commissioner and chief architect of the New York Police Department's heralded strategies for fighting crime, died Saturday after a long illness. He was 49.

When Maple became a top adviser to police Commissioner William Bratton in 1994, the city's annual homicide body count still topped 2,000. The year the Bratton team left, 1996, the homicide total dropped below 1,000; it fell to 629 the following year.

Maple wrote ``The Crime Fighter: Putting the Bad Guys Out of Business,'' a first-person account of his rise from self-styled dandy with a badge to crime statistic junkie to high-priced consultant.

In the book, Maple described how the police department of the early 1990s _ a ``dysfunctional'' force with too many cops working bankers' hours to combat crooks working around the clock _ became an efficient paramilitary machine that uses computer tracking of crime trends to deploy officers where they're most needed.

Philip Edward Rollhaus Jr.

PALM BEACH, Fla. (AP) _ Philip Edward Rollhaus Jr., the founder, chief executive and chairman of the Quixote Corp., died Tuesday of cancer. He was 66.

Rollhaus founded Energy Absorption Systems in 1969. He developed the company's patented highway cushions, which are designed to protect cars in crashes.

The holding company changed its name to Quixote in 1969 to reflect its interests in optical discs and court-reporting machines. A subsidiary, LaserVideo, which became DMI, made the first audio compact disc in the United States in 1975.

Quixote currently focuses on highway safety: its companies manufacture flexible signposts, devices to measure traffic flow and highway advisory radio systems. Rollhaus retired as president and chief executive last year, but remained chairman.
