A 16-year-old boy said he was “nervous” when he found a human skull in a Hollywood lake this weekend. 

Matthew Fischer and a friend discovered the skull at the bottom of a clay pot at about 5:30 p.m. Saturday in Oak Lake, near 56th Avenue and Douglas Street. 

The pot was under a shopping cart about 10 feet from shore. 

“He called me over to grab it, and I picked it up so he could get the rocks off, but the rocks weren’t falling off, and when I fully picked it up, the vase was under the cart,” Fischer said. “I put it back onto the ground, and I was like… So I got butterflies in my stomach because that was my first time ever seeing a skull. I was nervous.” 

The teens are Boy Scouts. Fischer said they were trying to do a good deed and clean up some of the garbage and debris in the water when they found the skull. 

“I grabbed the vase. He called me over, and I grabbed it. I was like, we better call the cops,” Fischer said.

"I know this lake. I want the kids to stay out of this lake," said Matthew Fischer’s mother, Brandy Fischer."This lake is dangerous. It's toxic. I told them to stay out of the lake. My son, being the boy he is, wanted to clean out the lake, thinking he can have Mom swim in it now. No -- he brought this skull home, and we called the cops, and that was it. It was nasty."

Hollywood police divers were in the water, searching for bones or other body parts. They concentrated on the floor of the lake. They said they did not find any more bones. 

They did find a couple of floor safes, but they think they are unrelated. 

The Broward medical examiner is trying to determine the race, gender and age of the person whose skull was found, as well as possibly the identity and the cause of death. 

A Hollywood police officer is stationed at the lake until the forensic anthropologist that was called in is sure there is no need for divers to go back into the water. 

Matthew and Brandy Fischer described the skull as small, possibly the skull of a young child, but investigators have not confirmed the size or age of the person.
