A Hammond woman is in critical condition after being shot in the stomach Sunday by a man she was allegedly trying to stab, authorities said.

Margaret Jackson, 47, remained in the hospital Monday as the Tangipahoa Parish Sheriff’s Office continued to investigate the incident, which occurred about 2:30 p.m. Sunday at a home on East Illinois Street, sheriff’s spokeswoman Dawn Panepinto said.

Jackson allegedly attempted to stab two people inside the Illinois Street residence before the man shot her, Panepinto said.

Additional information will be released as the investigation progresses, Panepinto said.
