LOS ANGELES -- A man charged with helping bomb a fertility clinic in California last month died after jumping off a balcony inside a federal detention facility in Los Angeles, local media reported on Thursday, citing sources familiar with the incident.

Daniel Park was found unresponsive at the Metropolitan Detention Center in downtown Los Angeles about 7:30 am Tuesday local time, the Los Angeles Times reported.

The Los Angeles County Medical Examiner has yet to announce a determined cause of death. Two sources, not authorized to discuss the death, told the biggest newspaper on the US West Coast that information gathered showed Park climbed onto a surface and then jumped off a high balcony, fatally injuring himself.

No one else was injured and no further details on the cause of death were immediately available, said the report.

Park, of Washington State, is facing charges after allegedly providing material support to the Palm Springs fertility clinic bomber by shipping and paying for significant quantities of ammonium nitrate -- an explosive precursor -- prior to the suicidal terror attack, according to the US Attorney for the Central District of California.

The 32-year-old was arrested on June 3 after his flight from Poland arrived at the John F. Kennedy International Airport in New York. Akil Davis, the Assistant Director in Charge of the Federal Bureau of Investigation (FBI) Los Angeles Field Office, said in a press release earlier this month that Park's contribution to the destructive device detonated on May 17 led to the charges.

According to an affidavit filed with the complaint, Guy Edward Bartkus, 25, of Twentynine Palms, California, drove a car containing a bomb to a fertility clinic in Palm Springs on May 17. Bartkus detonated the bomb, killing himself, injuring numerous victims, destroying the fertility clinic's building and damaging surrounding buildings and areas.

Authorities said the Bartkus attack was motivated by his pro-mortalism, anti-natalism, and anti-pro-life ideology, which is the belief that individuals should not be born without their consent and that non-existence is best.

Park, who shares the extremist views of Bartkus, shipped large quantities of explosive precursor materials to Bartkus, including approximately 180 pounds (81.7 kilograms) of ammonium nitrate. Days before the Palm Springs bombing, Park paid for an additional 90 pounds (40.8 kilograms) of ammonium nitrate that was shipped to Bartkus, according to the press release.
