WHITTIER – Coroner officials on Monday identified a woman who died after a large eucalyptus tree toppled onto a wedding party at Penn Park in Whittier,, killing the woman and injuring seven others, including a 4-year old girl who was hospitalized in critical condition.

Margarita Mojarro, 61, of San Pedro, was identified as the victim of the tragic accident, said Los Angeles County Department of Medical Examiner-Coroner Assistant Chief of Operations Ed Winter. Mojarro was a mother of four and grandmother of four, according to a family member, who asked for privacy.

Witnesses reported the group was taking pictures beneath the 100-foot-tall tree at Penn Park, 13950 Penn St. around 4:30 p.m. Saturday when it suddenly uprooted and fell. City officials are investigating what caused the tree at the city park to fall. They planned to send an arborist to the site Monday.

The park remains closed to the public.

“It’s an ongoing investigation,” said Assistant City Manager Nancy Mendez. “We’re taking steps to manage the incident.”

A Los Angeles County Fire Department spokeswoman said six adults and one child were injured in the incident, which has been ruled an accident.

“The important thing is to focus on the family, to let them know that this community is behind them, and that we’re praying for them,” Whittier Mayor Joe Vinatieri said.

“It was supposed to be one of the most exciting days of their lives, and instead, it turned into what it turned into,” he said.

It was too early to say what may have caused the tree to fall, according toCity Manager Jeff Collier.

“We can’t speculate until we have the arborist come out here and investigate,” he said.

Until then, officials will not remove the debris.

“We want to preserve the scene at this point. We want to make sure we have a chance to see everything as it exists today,” Collier said.

While the city already has an ongoing program to maintain and inspect trees, officials are also in the process of double-checking the integrity of the many other towering trees in Penn Park, Collier said.

The park, which is staffed by city officials seven days a week, is a popular site with wedding parties and other celebrations. Groups can often be seen posing for pictures beneath the park’s giant trees.

“What’s intrinsically wonderful about it is those trees,” Vinatieri said.

As the investigation progresses, “the important thing is to focus on that family,” Vinatieri said. “There’s an outpouring of concern, sadness and prayer.”

Injuries due to sudden tree falls are uncommon, but not unheard of in the region.

Eight children were injured, two of them critically, when an 85-foot-tall Italian stone pine tree toppled over at the Kidpace Museum in Pasadena on July 28, 2015.

That incident also occurred following a bout of heavy rain amid years of drought.

Saturday’s accident in Whittier took place within days of the Southern California’s first significant storm of the winter.

An arborist concluded the tree in Pasadena likely fell because it was taking in more water than it could release, increasing its weight, coupled with weak roots on two sides of the tree.

The family of 6-year-old twins injured in the incident has since filed a lawsuit against the museum alleging the incident was the result of negligence and failure to maintain the tree. Kidspace Museum subsequently filed a claim against the city of Pasadena, arguing that the city is liable for any legal costs or damages associated with the incident.
