A man was killed on Tuesday afternoon in a jet ski crash in Lowell, Massachusetts, according to the Middlesex district attorney's office.
Police responded to Rynne Beach on the Merrimack River at about 3 p.m. where the collision between two jet skis had occurred.
The victim was taken to an area hospital where he died from his injuries. He was identified Wednesday morning by DA's office as 39-year-old Juan Arroyo-Ortiz of Lawrence.
His family said the father of four was an avid jet skier and enjoyed working on cars.
"His kids, his wife was there and the only thing they know was that they pulled out that jet ski it was supposedly a collision," said Miguel Fernandez, Arroyo-Ortiz's brother-in-law.
So far, no arrests have been made and police have not said if they know the operator of the other jet ski.
Arroyo-Ortiz's family is pleading with the other jet skier to come forward.
"How can we get peace? Knowing the truth." said Fernandez. "It's not going to bring him back. It's not going to bring him back to us, but at least it gives us that knowledge and that closure that we need."
Authorities are asking anyone who may have witnessed the collision to contact state, environmental or local police.
Bob Howard, who owns a restaurant across from Rynne Beach, said the Merrimack River was crowded on the Fourth of July.
"I see more jet skis now than I have in the past," he said. "They go pretty fast. I don't see a lot of enforcement out there. It's been an issue."
The investigation is ongoing.
