Jon David Messner a Maryland-based operator of porn sites is best known for hacking into al Qaeda websites on behalf of the US Government. Messner, at 46, died this week.

Maryland- The man who sent flowers anonymously to every resident in the Berlin Nursing Home for Christmas died this week. That gesture was just one of several that Jon David Messner made without the recipients knowing the name of the giver.

He did not want his gifts or money turned down because of possible prejudice against him. He was best known as a pornographer, but he also used his computer savvy to work on national security issues and to hijack a militant Islamic website promoting the terror organization, al-Qaida.

His ability to use the Internet to investigate and to capture the site led to an invitation to speak at the country’s war college, the National Defense University. It was a highlight of his life.

Although he started spending most of his time monitoring several websites he set up to search for terrorist activity, he maintained the site that made him and his wife known around the world. Started from a corner in their Ocean Pines house, the website featured amateurs posing nude.

The site gained notoriety and the Messners were featured in national magazines and on many television shows, including Dateline NBS, plus shows in Europe. A film about them and their site was promoted at the Cannes Film Festival.

Messner branched out into more mainstream endeavors and owned an Internet Service Provider for a few years.

His success earned him millions and he was generous with his money. In 2001, he gave a limousine to charity and although that gift was written about, he said he usually liked to make donations anonymously. He just liked to do nice things for people, he said. He particularly enjoying sending flowers to people in the nursing home so they would know someone cared about them, he said.

He bought an Ocean City condominium and then his dream home in Lighthouse Sound in 2001. An accomplished artist and photographer, he put decorative finishes on many of the walls and then filled the home with his photographs. He loved the home, but it was that home, he would say, that led to his illness.

In a lawsuit filed against Monogram Building and Design and other firms last summer, Messner contended water got into the house and caused a mold infestation problem. He had photographs showing himself sitting in the living room holding an umbrella because of water entering the house.

Messner became ill, was hospitalized a number of times and had varying diagnoses. Eventually, he was told that the mold had made him sick.

In December 2003, the Messners left their dream home, which had become a nightmare and moved to an Ocean City apartment. He was too ill to run his pornographic website and the income was reduced to what he said was a moderate level.

He had respiratory and memory problems and did not expect to recover.

One benefit, he said, of the changes in his life since becoming ill was that his family had become closer. He cherished being with them, he said.

Messner seldom left his apartment, not wanting to be seen and not wanting to be pitied.

He ended his life on Monday. He was 46 years old. He is survived by his wife, Cherie, a son and a daughter.

Funeral services were to be private.
