An occasional karate trainer who police say told a friend that he had killed a Glen Burnie man has been charged with murder, Anne Arundel County police said Wednesday.
Joseph Samuel Serio, who lives in an apartment in the 7800 block of Bruton Drive in Glen Burnie, was ordered jailed without bail Wednesday on first-degree murder and related counts in the fatal shooting July 15 of Lamont Gordon Jr., 28.
Shortly after the killing - which led authorities to lock down nearby schools - witnesses told police they had seen a man chasing and shooting at Gordon. Gordon was found dead shortly after 7 a.m. in the 7900 block of Summer Rain Court, where he lived.
Two days later, witnesses told police that Serio had killed Gordon and fled to Miami, according to charging documents. Ballistics evidence found in his home linked him to the homicide, according to the charging paperwork.
Police declined to provide a possible motive, citing the continuing investigation. "There are more witnesses who need to come forward and there is more information that has to be gathered," said spokesman Justin Mulcahy.
Within a week of Gordon's slaying, a friend of Serio's told police that Serio admitted to killing Gordon, according to charging documents.
Serio was arrested July 21 on unrelated charges in Miami and was returned to Maryland on Tuesday. Warrants were served charging him with a March burglary, robbery and other counts; for not coming to court to answer accusations that he was behind on child support; and for traffic cases, court records show.
Serio recently worked about a month at Macon's Karate and Fitness in Odenton, sometimes helping with training and other duties, said the owner, Herman Macon. Serio had trained under him a few years ago and had a black belt, Macon said.
Macon described Serio as a "nice guy" and a carpenter by trade. He said, Serio sometimes had an attitude - "He was good, but he thought he was too good" - and did not display leadership qualities.
"He was just a little too cocky. It was more about him and not about the kids," he said.
He said Serio had left the area a year or so ago to pursue more karate training in California. He returned in recent months, coming by to train "every now and then" and working occasionally for Macon's center.
Serio had served four days for a 2003 assault conviction.
