New Orleans police on Monday released photos that they said show a suspect in the shooting at a Mother's Day parade in which 19 people, including two children, were wounded.

The image singling out the suspect does not clearly show the face, and police, who released the photographs on YouTube, asked for the public's help in identifying and finding the person.

Ten men, seven women and a girl and a boy, both 10 years old, were hit when one or more people opened fire at the parade on Sunday. Police had earlier said they were looking for three suspects, adding that a motive for the shooting was unknown.

The photographs first show crowds of people in a street, and then the crowd is seen scattering and ducking. The final image focuses on what appears to be a man in a white shirt leaving the scene on foot as other people are lying on the pavement. The image does not clearly show his face.

A police spokesman said on Monday the investigation was continuing.

Two victims underwent surgery and the children were grazed but in good condition, police said. It was unclear if the victims were marching or watching the parade.

Police Superintendent Ronal Serpas has said a witness reported hearing two different types of gunshots, indicating two weapons were involved.

Violent crime in New Orleans ranks above the national average in FBI surveys. A poll of residents in 2010 found crime to be their greatest concern.

【新闻快讯】

美国当地时间5月12日，路易斯安那州新奥尔良市母亲节游行队伍遭遇枪击事件，造成现场包括2名儿童在内的19人受伤，警方目前正在缉拿凶手。美联社消息称，枪击事件更可能是街头暴力，而非恐怖袭击。这是该市今年发生的第三起节日游行时疑犯向人群开枪的袭击案。

据美联社今日报道，新奥尔良警方已经通过安装在街头的监控摄像头获得了案发时的现场录像。警方称，颗粒感监控录像显示，游行队伍在遭到枪击之后，有人受伤倒地，人群立即往四处逃散，其中一名身穿白衬衣和黑裤子的持枪黑人男子立即从人群中跑走。

尽管录像上的形象并不很清晰，但警方肯定该黑人男子就是嫌犯并对外公开了视频，希望有人能认出嫌犯并报告警方。新奥尔良警方准备了一万美元的奖金给提供正确线索的举报者。

警方称，伤者大都是跌倒时的皮外擦伤，部分是被跳弹击伤。但路易斯安那州立大学医疗中心发言人今日告诉美国有线电视新闻网CNN记者：“入院接受治疗的伤者中至少有三名伤势严重。”
