Police in New York have appealed for help to identify a man who shot at least two homeless people, killing one as the victim slept on the street.
The attacker first shot a man, 38, in the US city's Lower Manhattan area early on Saturday, wounding him, investigators said.
Then shortly before 5pm, another man was found dead in a sleeping bag with gunshot wounds in his head and neck.
"The cases are clear and horrific," said Mayor Eric Adams, a former police officer, who urged witnesses to come forward.
Video surveillance footage captured that attack, showing the shooter firing at the second man as he slept at about 6am, shortly after the first incident.
On Sunday night, local media reported an attack on a third man, who also appeared to be homeless. He was found dead at around 7pm local time with a "possible gunshot wound," NBC New York reported, citing police.
Mr Adams described the shootings as senseless attacks on people "sleeping on the streets — not committing a crime, but sleeping on the streets."
He and the police urged New York's thousands of homeless people to contact city agencies that can help them find sleeping accommodation.
Homeless people moved out of subways
New York's homeless population has grown in recent years. Mr Adams announced a plan only weeks after taking office in January to move them out of the city's vast system of subway tunnels, where many sleep on cold nights.
His proposal drew sharp criticism from some non-governmental organisations.
"People only stay in the subway because they have no better place to go," said the Coalition for the Homeless.
The appeal comes after a stabbing at New York's Museum of Modern Art on Saturday, when a man leapt over a reception desk and stabbed two employees as they tried to flee.

Start-up hopes to end Japan's love affair with cash
Across most of Asia, people pay for taxi rides, restaurant meals and merchandise with smartphone-readable barcodes — except in Japan, where cash still rules. Now, as the country’s biggest web companies race to dominate the payments market, one Tokyo-based startup says it has a fighting chance to win with its QR app.
Origami had a head start when it introduced a QR-code payment service in late 2015 and has since signed up fast-food chain KFC, Tokyo’s largest cab company Nihon Kotsu and convenience store operator Lawson. The company raised $66 million in September to expand nationwide and plans to more than double its staff of about 100 employees, says founder Yoshiki Yasui.
Origami is betting that stores, which until now relied on direct mail and email newsletters, will pay for the ability to reach customers on their smartphones. For example, a hair salon using Origami’s payment app would be able to send a message to past customers with a coupon for their next haircut.
Quick Response codes, the dotted squares that can be read by smartphone cameras, were invented in the 1990s by a unit of Toyota Motor to track automotive parts. But when the Japanese pioneered digital payments almost two decades ago with contactless cards for train fares, they chose the so-called near-field communications technology. The high cost of rolling out NFC payments, convenient ATMs and a culture where lost wallets are often returned have all been cited as reasons why cash remains king in the archipelago. In China, however, QR codes dominate.
Cashless payments, which includes credit cards, accounted for just 20 per cent of total consumer spending in Japan during 2016, compared with 60 per cent in China and 89 per cent in South Korea, according to a report by the Bank of Japan.
