New Castle County police were dispatched to the 300 block of Camerton Lane for a report of an injured person yelling for help around 4 p.m. on Dec. 3. Officers found a 68-year-old man on the front steps with multiple stab wounds.

Inside the home, officers found a 61-year-old woman, a 53-year-old woman and a 19-year-old man who all died from their injuries, according to the New Castle County Police.

Officers determined the suspect fled in the victim's red pick-up truck and identified the attacker as 40-year-old Donald Grier Jr. Police found Grier and tried to stop his vehicle, but he fled.

Grier reportedly struck several other vehicles, including a police vehicle, before coming to a stop. Authorities placed Grier into custody and took him to a local area hospital for minor injuries.
