DULUTH — A preliminary manslaughter charge has been dropped for the suspect accused of fatally punching another man in the Lakeside-Lester Park neighborhood, but he will still remain in custody for the immediate future.
Anthony Thomas Laspina, 46, has been in the St. Louis County Jail since early Saturday, when he allegedly struck and killed Ryan Arthur Roessler, 42, during an argument at 105 N. 54th Ave. E.
After receiving a one-day extension Wednesday, the St. Louis County Attorney's Office did not file a formal criminal complaint Thursday. Nate Stumme, head of the agency's Duluth criminal division, told the News Tribune that the investigation "is still active" and did not provide any timeline for a charging decision.

But Laspina did appear in State District Court on Thursday morning to face an alleged probation violation stemming from the fight. He remains under supervision through November 2023 for an April 2020 incident in which he reportedly attacked and threatened several neighbors and police officers.
Laspina formally denied the probation violation. But with Judge Shawn Pearson ordering him to remain jailed pending further proceedings, the move essentially buys time for prosecutors to consider potential homicide charges.

Roessler was found on the floor at Laspina's home and pronounced dead shortly after police were called at approximately 12:50 a.m. Saturday. Authorities said they learned the two men had been in a verbal argument and that Laspina punched the victim in the head, knocking him unconscious.
Laspina was taken to the Public Safety Building in Duluth, where he allegedly "caused damage to the interview room," before he was taken to jail on a preliminary charge of first-degree manslaughter.

Laspina received a stay of adjudication following the 2020 case, which would allow three felony counts of making threats of violence to stay off his record upon successful completion of three years of supervised probation.
Authorities said in the complaint that he chased a neighbor with a knife, also throwing the weapon at the victim, before barricading himself inside a basement workshop and repeatedly striking a police dog during his arrest.
Court documents state that Laspina "has a long history of physical violence due to mental illness, particularly when methamphetamine use is present." A judge had granted him the break from state sentencing guidelines due to his "demonstrated commitment to chemical dependency and mental health treatment."
