An 18-year-old man was arrested overnight in connection with Saturday night’s double shooting in Columbia that left one teenager dead and another in critical condition.

Howard County Police said Sunday that Emmetson Zeah of Columbia was arrested and charged with first-degree murder, attempted first-degree murder and related offenses. Police said they recovered a gun and clothing worn during the shooting at the suspect’s home.

The shooting killed 16-year-old Michael Robertson of Columbia, who is listed online as a sophomore football player at Wilde Lake High School. A Howard County Public Schools spokesperson confirmed his enrollment there.

“Michael was a well-liked student, friend, classmate, and football teammate, and his death will likely have an even greater impact on many people because it was a homicide,” Wilde Lake Principal Michael Brown said in an email sent to the school community Sunday night.

He said teachers will share the news with students on Monday morning, and staff members with meet with the football teams as a group “to help them process.”

He shared mental health resources for parents and said he would update the community on funeral services based on the family’s wishes.

Police said the other victim, a 15-year-old boy, also of Columbia, was shot and transported to the University of Maryland Shock Trauma Center, where he remains in critical condition.

Police spokesperson Seth Hoffman referred questions about the shooting victims and the suspect to Howard County Public Schools. School system spokesperson Brian Bassett confirmed that the 15-year-old teen attends Oakland Mills High School while the suspect is a student in the system’s “Passages program,” which provides support services for students transitioning back into “comprehensive school.”

In an email Sunday, Oakland Mills Principal Jeffrey Fink said the family of the injured 15-year-old said he is “currently in the hospital in critical condition.”

Fink said any information about the student’s condition will be shared based on his family’s wishes.

Superintendent Bill Barnes said in an email Sunday night that the impact of what happened can be felt across the school system, and staff across the district are prepared to provide support to any student who needs it.

“Today, we are grieving with the families, friends, and all those closest to this tragedy,” Barnes said.

Online court records show Zeah faced criminal charges in December and was initially ordered to be held without bond, but was released three days later on a $50,000 bond. He then was granted private home detention, which began Jan. 8.

Two days ago, though, Zeah received a notice that he had violated pretrial private home detention, online court records show. Police said Sunday afternoon that they also have charged him with attempted first-degree murder for a Feb. 14 incident in Columbia in which he “fired several shots” but didn’t strike anyone. That incident happened in the 10200 block of Twin Rivers Road, less than a mile from Saturday’s shooting.

The Saturday shooting happened shortly before 6 p.m. close to The Mall in Columbia in the 10300 block of Little Patuxent Parkway near a bus stop and a Lidl grocery store, Police Chief Gregory Der said.

The shooting appears to have been targeted, he said, and the suspect acted alone. Detectives were interviewing witnesses and reviewing surveillance video.

Zeah is being held without bail at the Howard County Detention Center. Online court records do not list an attorney. A bail and bond review hearing is scheduled for Monday morning.

This is the second homicide in Howard County this year.

Seventeen-year-old Lance Carrington was shot and killed while sitting in a vehicle in Columbia on Jan. 14. Howard County Police have arrested three teenagers and are searching for a 16-year-old suspect believed to have fired the fatal shot before fleeing with the others.
