The man who supplied the Palm Springs fertility clinic bomber with the ammunition used in the attack reportedly died after jumping from an upper level of the prison.
Daniel Park, 32, was found unresponsive inside the Metropolitan Detention Center in Los Angeles about 7.30am Tuesday morning.
According to TMZ, he stepped up onto a table on an upper tier of the detention center and jumped off the balcony, plummeting to the ground floor.
It is unclear how many stories he fell.
Prison authorities attempted to save his life and he was rushed to hospital, where he was later declared dead.
Park, of Seattle, Washington, was accused of supplying 180lbs of explosives to Guy Edward Bartkus, the bomber who died in the May 17 explosion at the American Reproductive Centers.
Park was taken into custody at New York’s JFK Airport by the FBI and Port Authority Police on June 3 following the explosion. He had been deported back to the US from Warsaw, Poland.
He was a US citizen, though it is unclear if he has any connections to Poland, US District Attorney Bilal A Essayli said.

Bartkus, the primary suspect and man accused of setting off the bomb, was killed in the explosion after a silver Ford Fusion sedan erupted.
Earlier this month, FBI director Akil Davis said the agency discovered that Park shipped six packages of ammonium nitrate – a chemical compound found in bombs – from Washington State to Bartkus in California.
Park was also ‘in possession of a similar recipe’ that was used in the 1995 Oklahoma City bombing, Davis said.
Davis described both Park and Bartkus as members of the anti-natalist movement, a group that ‘don’t believe people should exist’ and people should not continue to procreate.

The FBI believes the two were conducting experiments in a garage in Twentynine Palms – a large US Marine Corps base that Bartkus lived in.
At least five others were injured in the incident, which authorities called an ‘intentional act of terrorism.’
The bomb recipe that Park was in possession of was similar to that of the Oklahoma City bombing – where Timothy McVeigh, a former Army soldier and security guard, set off a powerful bomb inside a rented truck in front of the Alfred P. Murrah Federal Building in downtown Oklahoma City.
A total of 168 people were killed, including 19 children. Several hundred more injured.
In his writings, IVF clinic bomber Bartkus allegedly said he was ‘pro-mortalist’, something he described as someone who intends to bring on their own death as soon as possible ‘to prevent your future suffering, and, more importantly, the suffering your existence will cause to all the other sentient beings.’
He also recorded a 30-minute-long audio clip explaining why he ‘decided to bomb an IVF building, or clinic.’
Multiple witnesses reported hearing a loud boom, and dramatic videos shared on social media show the explosion shattered the windows of a nearby liquor store
‘I figured I would just make a recording explaining why I’ve decided to bomb an IVF building, or clinic. Basically, it just comes down to I’m angry that I exist and that, you know, nobody got my consent to bring me here,’ he said.
Bartkus also said he was ‘angry’ that IVF clinics exist, adding: ‘These are people who are having kids after they’ve sat there and thought about it. How much more stupid can it get?’
He is suspected of setting off a large vehicle-borne improvised explosive device outside of the clinic, which performs IVF treatments, egg collections and other procedures, according to his website.
Authorities found an AK-47 and an AR-Style rifle, as well as ammunition next to the burnt vehicle, the LA Times reported.
He allegedly tried to film the terror attack by setting up a tripod with a camera beforehand, but the file failed to upload to his website, according to BNO News.
On the day of the attack, FBI officials raided his home and evacuated the neighborhood over fears it was a ‘blast zone.’
At the time, Davis said the agency was running the investigation, but did not specify if the raid was connected to the fatal explosion.

Following the powerful explosion, Davis confirmed it was a terror attack.
‘Make no mistake: This is an intentional act of terrorism,’ Davis said during an evening news conference.
Multiple witnesses reported hearing a loud boom, and dramatic videos shared on social media show the explosion shattered windows of a nearby liquor store.
Dr. Maher Abdallah, who operates the American Reproductive Centers fertility clinic, confirmed to The Associated Press that his facility was among the properties damaged in the blast.
He said all staff members were safe and accounted for.
The explosion impacted the office area used for patient consultations but did not harm the IVF laboratory or any of the stored embryos.
‘I really have no clue what happened,’ Dr Abdallah said. ‘Thank God today happened to be a day that we have no patients.’
None of the facility’s embryos were damaged in the attack.
Daily Mail contacted the Metropolitan Detention Center and the FBI for comment.
