Kansas City, Mo. ? The man accused of fatally shooting two women and four of his children before taking his own life Saturday had been depressed and acting irrationally for weeks, Kansas City police said Sunday.

Police identified the shooter Sunday as Hersel M. Isadore, 35. His body was found in the kitchen of his home with a revolver nearby. No suicide note was found at the scene, said police Capt. Rich Lockhart.

Isadore killed 35-year-old Alisandria G. Davis on Saturday morning at her home, police said. Witnesses said Davis was Isadore’s cousin.

He then went to his own house, where police said he shot his longtime girlfriend, Shanika King, 32, and four of their children.

King’s aunt Janna Walker said Isadore called King’s mother and told her, “I’m tired of being picked on and I just shot everybody in the house.”

The bodies of King and their youngest child, MyKzee Isadore, 13 months, were found in a bed. The body of Amaya King, 14, was found in another bedroom, while the body of Dovian King, 8, was found in the basement. All had been shot, police said.

A fourth child, Marquill King, 11, was found alive in the basement and rushed to a hospital with a gunshot wound to the face. Police said Sunday that he had died.

Police on Saturday had reported it was Dovian who survived, but said the mistake came because Marquill’s injuries made it difficult for family members to identify him.

Two of the couple’s other children had spent the night at their grandmother’s house, said police and relatives in the neighborhood of low- to middle-income, single-family homes, about five miles east of downtown Kansas City. They’re now staying with family, police said.

Neighbors and relatives painted a mixed portrait of Isadore, saying that while the family appeared happy and the home was a frequent gathering spot for neighborhood children, Isadore had been acting depressed for some time and could be controlling and “bossy” with King, whom he had dated since she was 13 and he was 16.

His grandmother, Annie Blackwell, said Isadore, whom everyone called Michael, loved his children and regularly called to check on her.

“He was a beautiful person,” Blackwell said. “We didn’t even know there was something wrong.”

Santaya Wiley, King’s sister, said Isadore had a steady job at a Wal-Mart in Johnson County, Kan.

“He’s not a harsh person,” Wiley said. “This was totally out of character. : This is unbelievable.”
