A jury was seated late Monday in Baltimore County Circuit Court for the trial of a Cockeysville man accused of shooting two county police officers.

Potential jurors gathered in a windowless ground-floor room of the courthouse in Towson for hours Monday, fielding questions about if they could be impartial and what views they hold about police, mental health and other topics. Thirteen of the dozens gathered said they had previously heard of the case.

David Linthicum, the 25-year-old defendant, attended jury selection in person, wearing a suit and seated between his attorneys.

Sixteen people, a 12-person jury and four alternates, were selected shortly before 6 p.m.

Authorities say Linthicum shot two police officers in February 2023 and led them on a two-day hunt and pursuit across two counties. A police officer responding to a call about a suicidal person went to Linthicum’s bedroom, where the defendant allegedly fired 15 rounds and fled into the woods behind his house. He was apprehended in a stand-off in Fallston nearly two days later, after allegedly shooting another officer he came across during the police search for him.

He is charged with five counts of attempted first-degree murder, seven counts of assault and numerous firearms offenses, according to an online courts database. The trial against him is expected to last about 10 days, Associate Judge Garret P. Glennon Jr. told prospective jurors.

Glennon told the jurors, once they were selected, to “do no research of any kind, whatsoever.” It is vital, he said, for the jury to decide based on evidence heard together in court.

The trial comes after a judge last week denied a motion to postpone filed by Linthicum’s attorneys, Deborah Katz Levi and James Dills. They had sought a postponement to allow more time for the court to consider their push to have the case dismissed. Circuit Judge Robert Edward Cahill Jr., however, said the community deserved a trial and declined to postpone it.

Linthicum’s attorneys are expected to argue that the police response to Linthicum’s mental health crisis in February 2023 was flawed. They have said in court filings that officer mishaps amounted to a “grossly reckless response.”

Levi, the director of special litigation for the Office of the Public Defender, and Dills, district public defender for Baltimore County, also have accused prosecutors of withholding police files from the defense, having a bias against Linthicum and prosecutorial misconduct. The allegations include that the Baltimore County State’s Attorney’s Office donated $2,722 to an online fundraiser for one of the officers.

Assistant State’s Attorney Zarena Sita, who is prosecuting Linthicum alongside Deputy State’s Attorney John Cox, said in court last week that the defense’s motion to postpone was unfounded and rehashed points already decided by a judge who sided with prosecutors.

Sita said prosecutors want to resolve cases in a timely manner, and that defendants have the right to a speedy trial.

“There are victims in this case,” she said last week, “victims who have a desire to have this case resolved.”
