A Massapequa man will serve 20 years to life for the murder of a teaching assistant.

Ryan Lindquist was sentenced Wednesday after pleading guilty to murder last month.

Prosecutors say the 23-year-old stabbed Evan Grabelsky more than 150 times in Merrick in June 2019.

Officials say the two men had been in a romantic relationship for about a year.

According to police, the suspect and the victim had known each other for about two years, and they first met using a social media dating app.
