A 72-year-old man suspected of killing 10 people in a mass shooting at Monterey Park in California has died from self-inflicted injuries, authorities say.
Los Angeles County Sheriff Robert Luna said Huu Can Tran was found on Sunday after police reportedly heard a single gunshot from inside his vehicle.
The breakthrough comes after police released the man's photo and surrounded a white van more than 30 kilometres away from where the shooting happened on Saturday night.
Let's take a look at how the mass shooting happened and how the manhunt played out.
Shots fired, screaming heard
The shooting happened about 10.22pm local time on Saturday at the Star Ballroom Dance Studio in Monterey Park.
The suspect entered the ballroom dance and opened fire.
Five women and five men were killed and at least 10 people have been left injured.
Mr Luna said the victims appeared to be over 50 years old but did not provide specific ages.
Mr Luna said seven people remained in hospital.
People were "pouring out of the location screaming" when police arrived, Los Angeles County Sheriff's Department Captain Andrew Meyer said.
The shooting was near a two-day event to ring in the Year of the Rabbit, which attracted tens of thousands of people.
Monterey Park is a city of about 60,000 people and is 11 kilometres from Los Angeles.
About two-thirds of its residents are Asian, according to US Census data, and the city is known for its many Chinese restaurants and grocery stores.
Gunman enters second ballroom
About 30 minutes after the shooting at Monterey Park, the suspect entered the Lai Lai Ballroom in nearby Alhambra.
Mr Luna said the suspect was disarmed by two people who wrestled a semiautomatic pistol with an extended magazine off him.
He said the people who took the weapon off the suspect were "heroes" and their actions saved lives.
The gunman fled the scene.
Public appeal as suspect is identified
Eyewitnesses told police the shooter was an Asian man between 30 and 50 years old.
He was still at large 12 hours after the attack.
On Sunday morning police released images of the suspect taken from surveillance camera footage.
The photos showed him wearing glasses, dressed in a dark jacket and a dark beanie hat with white stripes.
Mr Luna said the man was considered "armed and dangerous" and the images were released in an attempt to identify him.
Search begins for white van
Authorities were looking for a white van after witnesses reportedly saw the suspect flee from Alhambra in such a vehicle.
Mr Luna said a man resembling the suspect had been seen in Torrance, which is about 34 kilometres away from where the shooting happened.
Police hear gunshot, surround van
Mr Luna said police located the van at 10.20am (local time) on Sunday in Torrence.
When they pulled behind the vehicle, officers heard one gunshot from within the van, Mr Luna said.
The officers retreated and called for tactical teams to respond.
Television images showed a body slumped over the steering wheel of that van.
At 12.52pm local time, police approached the van and found that the man had died from a self-inflicted gunshot wound, Mr Luna said.
Mr Luna said inside the vehicle there were several pieces of evidence that linked the man to both locations.
A handgun was found inside the van, but Mr Luna said it was believed the pistol that was taken off the suspect at Alhambra was used in the shooting.
There are no outstanding suspects, Mr Luna said.
Torrance Mayor George Chen praised the "very quick reaction" by police.
The questions that remain
Authorities are now turning their attention to uncovering the motive behind the shooting.
Mr Luna said the motive behind the "extremely tragic event" was not clear and it was "something we want to know".
"We want to know how something this awful can happen," he said.
California congresswoman Judy Chu said it was important to understand his motive and how he acquired the weapons.
"How did he gets these guns and was it through legal means or not?” she asked.
