HEMPSTEAD - Officials say more testimony is expected today in the trial against a woman accused of beating a Hempstead middle school teacher.

The teacher, Catherin Englehardt, is expected to be back on the stand today.

Last week, the jury saw surveillance of Englehardt being knocked out by an angry mom.

The mother, Annika McKenzie, is accused of punching Englehardt then putting her in a headlock until Englehardt collapsed last year.

McKenzie’s lawyer claims the teacher pushed McKenzie's daughter with a lacrosse stick.

Englehardt denies those claims.
