From a compound in Lahore, Pakistan to a home in the quiet Brad Drive neighborhood in Rockville, there's growing concern about the fate of kidnapped American contractor Warren Weinstein.
"It's just a Byzantine world, it's not straight up", says Chis Meyers, a neighbor and a widely travelled retired marine.
"There's people who are going to pick out Americans", he adds.
Authorities say Weinstein, 70, an industrial development expert, employed by Arlington-based J.E. Austin associates was kidnapped around 3:45 Saturday morning Pakistani time.
Police say eight to ten men approached Weinstein's Lahore house on a ploy.
"They had come up to the house", says Rockville neighbor Elsie Sullivan.
"They wanted to share food, and when they got in, they grabbed him."
Pakistani Police say Weinstein was forcefully taken away.
Reports say his abductors had tied up Winstein's three guards, and pistol-whipped his driver.
Landscapers working at Weinstein's Rockville home, which he shares with his wife Elaine, are concerned for the couple, who often travel together.
"This is a big surprise for me", says Willam Nicholls. "I don't know how she's ggoing to take the news, you know".
Nicholls says he last spoke with Mrs. Weinstein last Wednesday.
No one answered the door on Saturday.
Police say Weinstein had told his Lahore house staff that he was planning to return to the U.S. on Monday.
"I hope he comes home, I'll pray for him", says Meyers.
"I hope these aren't some of the crazy radicals out there. I hope he doesn't end up like Daniel Pearl."
Pearl was the Wall Street Journal reporter who was abducted and killed by al-Qaeda in Pakistan in 2002.
The State Department is urging Americans living in Pakistan to take safety precautions.
So far, no one has claimed responsibility for Weinstein's kidnapping.
Warren Weinstein, American contractor, abducted in Pakistan
LAHORE, Pakistan (AP) - Gunmen abducted an American after breaking into his house in the eastern Pakistani city of Lahore on Saturday in an unusually brazen raid that illustrated the threat to foreigners in this militancy-wracked, U.S.-allied country.
The U.S. Embassy identified the victim as Warren Weinstein. A man by that name serves as the Pakistan country director for J.E. Austin Associates, a development contractor that works with the aid arm of the American government, according to a profile on the LinkedIn networking website.
Pakistani police said the American was believed to be in his 60s, and had returned to Lahore the previous night from the Pakistani capital, Islamabad. He had told his staff that would be wrapping up his latest project and moving out of Pakistan by Monday, police official Tajammal Hussain said.
The profile says Weinstein is based in Lahore and has been in Pakistan for seven years. Calls to the company headquarters in Virginia were not immediately answered, but its website describes Weinstein as a development expert with 25 years experience and a Ph.D. in international law and economics.
His company's website says he was in charge of a program that has been trying to help strengthen the competitiveness of various Pakistani industries.
"He's a short, funny man with a quick wit," said Raza Rumi, a Pakistani journalist who last saw Weinstein about a year ago and said he could speak a fair amount of Urdu. "He's a very laid-back guy, not too worried about security issues, not really paranoid at all."
According to Pakistani police, between eight and 10 assailants broke into the American's house in an upscale neighborhood in Lahore after persuading the guards to open the gate by saying they wanted to give them food - an act of sharing common during the Muslim holy month of Ramadan.
Police declined to speculate on the motive behind the abduction. However, militant organizations frequently target foreigners in Pakistan, although it is rare for assailants to stage such a raid on a victim's home.
Kidnappings for ransom also are common in Pakistan, with most of the victims being Pakistani. Criminal gangs are suspected in most of the abductions, though militant groups also are believed to use the tactic to fund themselves through ransoms.
The Pakistani Taliban claim to be holding a Swiss man and woman kidnapped earlier this summer as they were traveling through a remote southwestern region. The militant group, which is based in the northwest tribal belt bordering Afghanistan, has demanded that the U.S. free a Pakistani woman convicted of trying to kill Americans in exchange for the Swiss pair's freedom.
Americans in Pakistan are considered especially at risk from militant attack because the insurgents oppose Islamabad's alliance with Washington and the U.S.-led war in Afghanistan. U.S. diplomats, aid workers and others are urged to take strong security precautions.
Ties between Washington and Islamabad plummeted after an American CIA contractor in January shot dead two Pakistanis he said were trying to rob him.
The American was held in a jail in Lahore for two months despite Washington's insistence he was immune from prosecution because he had diplomatic status. He was eventually freed after the victims' families were given compensation.
Lahore is the capital of the eastern Punjab province, a region bordering India that is home to several of Pakistan's top militant networks, some of which are suspected of ties to Pakistani intelligence. Major attacks in Lahore include a 2009 ambush of Sri Lanka's cricket team that killed six police and a driver.
The unilateral American raid that killed al-Qaida chief Osama bin Laden on May 2 in the northwest Pakistani town of Abbottabad further soured ties between the two countries and led to increased scrutiny on Americans living in Pakistan.
Earlier this week, the U.S. State Department issued a travel warning for its citizens saying that American diplomats are facing increased harassment and they, along with aid workers and journalists, have been falsely identified as spies in the local media.
Still, American lawmakers and officials have made a slew of trips in recent weeks to try to maintain the relationship with Islamabad.
On Saturday, U.S. Sen. John McCain arrived in Islamabad and met with top officials including Pakistani Prime Minister Yousuf Raza Gilani. In a statement afterward, Gilani said he told the Republican lawmaker that Pakistan desires an enduring partnership with the United States.
