Santa Clarita officials canceled a summer camp Tuesday, after a camp supervisor allegedly left children in triple-digit heat, officials said.

Julie Wolfe dropped off her 7-year-old son at one of several camps he attends over the summer, a Movies by Kids camp through the Seasons catalogue called “Minecraft Movie Making.”

When she arrived to pick him up, she’d found out a camp counselor allegedly left about 15 of the children, age 7-12, unsupervised for approximately 20 minutes at Valencia Glen Park on Monday, she said.

She arrived at the park around 4:15 p.m. and was told the counselor had left at 3:55 p.m., and the camp’s classroom was left unsecured. A statement from city officials noted there was a half-hour gap in supervision.

The city issued several statements in response to complaints that were filed by parents:

“This is absolutely unacceptable and not in line with the standards the city expects of its contractors,” said Gail Morgan, city of Santa Clarita spokeswoman.

“Minecraft Movie Making is one of five camps offered by Movies by Kids, a contracted company with the City of Santa Clarita…” the statement continued. “The City of Santa Clarita has taken immediate action and discontinued the relationship with Movies by Kids. The remaining four summer camps previously contracted with Movies by Kids have been cancelled and registrants will receive full refunds.”

The statement also mentioned an 11-year relationship with the camp and its programs that were incident-free. City officials also filed a report with the Santa Clarita Valley Sheriff’s Station in response to the complaint.

The counselor was reportedly fired shortly after the incident, according to Wolfe, who spoke with the owner of Movies By Kids, John Kindseth.

Kindseth said Tuesday morning that he had just met with city of Santa Clarita officials, and he had already called all of the parents to apologize.

“After 30 years of teaching kids in our movie camp program, we’ve never had an incident like this occur,” Kindseth said. “We’re absolutely devastated by this — our sincerest apologies go out to all the parents.”

Kindseth confirmed that the employee was terminated Monday, after he had received information from the employee that was different than what was reported to him by the city and parents.

“We absolutely do want to respond appropriately to this,” Kindseth said, noting he was also planning to apologize on social media, which is where many saw and commented on a post about the complaint yesterday afternoon.

Individuals or organizations wishing to offer a class or camp through the City of Santa Clarita are required to complete a Class Proposal Form, attend an interview with City staff, and submit references. The City evaluates the effectiveness of the contract camps annually.

The city of Santa Clarita runs approximately 1,100 contract classes per year, works with approximately 100 contractors and has not had any such issues with contract classes.

“The city wishes to extend its sincerest apologies to the families impacted by this incident,” according to a statement by city officials.
