JONESBORO, Arkansas (AP) -- Police say a gunman who shot and killed three people and injured four in northeast Arkansas was an acquaintance or friend, but a motive is unknown.
Jonesboro Police Sgt. Doug Formon says the shooter was 40-year-old Porfirio Hernandez, who recently had been released from a mental health treatment facility.
A 38-year-old man and a 12-year-old girl were killed Saturday afternoon at a home in Jonesboro, and four others were injured. About 20 minutes later, police received a call about a shooting at a business, where a 31-year-old man was found dead.
Hernandez was later found dead of an apparent self-inflicted gunshot wound.
Three people are in critical condition in Memphis, Tennessee, hospitals: a 43-year-old man, a 36-year-old woman and an 8-year-old boy. A 10-year-old boy is in stable condition.
Arkansas police say a man suspected of fatally shooting two people inside a home and a worker at a business has been found dead inside a stopped car.
Jonesboro Sgt. Doug Formon says a man and a 13-year-old girl were killed Saturday afternoon inside the residence in east Jonesboro. Four people -- including two boys -- were injured and were taken to hospitals in Memphis, Tennessee.
Formon says it appeared a family was having a party or gathering.
A few minutes later, authorities responded to a shooting at a business near a U.S. highway where a worker was found shot to death.
The man Formon says is the suspected gunman was found in the driver's seat of a stopped car. It wasn't clear if the gunshot was self-inflicted.
