A soccer coach who a California family says was the last person who had contact with their dead son is a person of interest in the boy’s disappearance and was arrested on an unrelated sexual assault case … TMZ has confirmed.

Missing 13-year-old boy Oscar Omar Hernandez was found dead in a ditch earlier this week in Oxnard and his family says he was last seen with his soccer coach, 43-year-old Mario Edgardo Garcia Aquino.

Our law enforcement sources tell us … Aquino was questioned by cops and was arrested … but not for Oscar’s death or disappearance.

Aquino is facing one count of assault with intent to commit another felony, which prosecutors allege was the attempted rape, sodomy or oral copulation of a man for the 2024 sexual assault case … according to NBC4, which was first to report Aquino’s arrest.

The alleged sexual assault reportedly went down in February 2024 … with LASD’s Special Victims Bureau investigating.

Oscar’s body was found in Oxnard but he’s from the San Fernando Valley in L.A.

The Connecticut donut shop under fire — mostly by trolls — after Blake Lively worked a shift without wearing a hairnet is cleared of any health code violations, TMZ has learned.

According to a Wilton Health Department document, which TMZ has seen, Rise Doughnut — a small mom-and-pop biz — was investigated after an “anonymous” complaint, and officials found zero violations. No fine was issued and the case is officially closed.

The department visit was trigged after people online were pissed Blake didn’t put on a hair net, hat or tie back her hair while working and serving up the treats — and as a result, they trolled the shop’s Yelp page. And, at least one person filed an official complaint.

The barrage of negative reviews became so abusive — left by people from all around the country — the shop’s Yelp Page had to be temporarily disabled, with Yelp explaining they’re investigating “whether the content you see here reflects actual consumer experiences rather than the recent events.”

While some people might have had a legit bone to pick for sanitary concerns … it’s safe to assume others were simply hating on Blake because of her ongoing legal war with Justin Baldoni.

A source close to Blake told us … “The so-called complaints are from people who have never been there and who don’t even live in Connecticut. Targeting a lovely, small, family-owned business is a new low in the retaliation campaign.”

Barack Obama is getting candid about his relationship with his wife Michelle Obama … and revealing some of their marital challenges.

The former president was talking to students at Hamilton College on Thursday when he told the crowd he “was in a deep deficit with my wife” after 8 years in the White House.

Barack added … “I have been trying to dig myself out of that hole by doing occasionally fun things.”

In March alone, we saw Barack at a Los Angeles Clippers game and out to dinner in L.A. without Michelle … and she wasn’t with him at Jimmy Carter‘s funeral or Donald Trump‘s 2025 Inauguration.
