Police: Man Dies After Drinking Buddy Pushes Him Into Charles River

A Massachusetts man whose friend died after he was pushed into the Charles River says the death was a prank gone horribly wrong.

Lenny Quintero-Flores, of Malden, was held on $25,000 bail Wednesday after pleading not guilty to manslaughter in connection with the death of 26-year-old Mitchell Harrison, of Watertown.

Police say the men were drinking on a Boston dock Tuesday when Harrison, either sleeping or passed out, was pushed into the water. Quintero-Flores told police he was unaware Harrison was unconscious.

Harrison was underwater for 10 and 30 minutes. He later died at the hospital.

The 27-year-old Quintero-Flores said outside court that Harrison was his best friend and he was "just playing around."

Quintero-Flores' public defender, M. Barusch, says there was no argument between the men before Harrison's death.
