The ex-Massachusetts State Police captain who’s facing charges in connection with a Dedham teenager drowning in his backyard pool last summer officially has a trial date.

James Coughlin and his wife, Leslie, hosted a graduation party at their Dedham home last June when 17-year-old Alonzo Polk drowned. The Coughlins are both facing two charges in connection to the incident: reckless endangerment of a child and furnishing alcohol to minors.

On Wednesday in Dedham District Court, the Coughlins asked for a trial date. The court set a final status conference for Jan. 9, and a trial date of April 3 — more than 660 days after Polk drowned at the boozy grad party.

Sometime before midnight on June 5, 2021, the Coughlins and other adults attending the graduation party went inside the home, leaving the teens outside by the pool. Several of the teens were intoxicated, according to police.

The pool area was very dimly lit, and an underwater light did not appear to be working.

Many of the teens began jumping into the pool. Polk and two friends were standing near the deep end, and they ultimately went into the pool.

His two friends eventually got out, and after a few minutes, they could not find Polk. One teenager became concerned, dove into the pool, and found Polk submerged underwater. He was pulled from the pool and CPR was performed on him before he was rushed to the hospital. Polk died a few days later.

He died as a result of “complications of drowning,” according to his death certificate, which does not mention alcohol as a cause of death. Some witnesses saw Polk with a drink, though toxicology reports revealed his blood alcohol concentration was less than .01% shortly after he arrived at the hospital.

While Polk wasn’t intoxicated, the Coughlins’ “furnishment of alcohol directly contributed to the risk of substantial injury,” the DA’s Office argued in a previous court filing.

The Coughlins have pleaded not guilty to both counts, and had been trying to get the reckless endangerment charge tossed.

“The facts of this case revolve around an absolute tragedy — a young man ten days’ shy of his eighteenth birthday drowned at a high school graduation party hosted by the Defendants,” the Coughlins’ defense attorney Brian Kelly wrote in a prior court filing. “But as the Supreme Judicial Court has made clear, the fact that a minor died in an accident does not mean that there is probable cause the defendants engaged in reckless or wonton conduct that endangered the life of a child.”

In the spring, a Dedham District Court judge rejected their bid for the charge’s dismissal.

On Wednesday, Kelly told reporters outside the courthouse that the Coughlins have been getting harassed at their home. He added that he has a video, which he plans to release next week in an effort to get the public to identify the alleged harassers.
