A man killed his two young children before killing himself in a double-murder-suicide in his home in Arkansas, police said.

Little Rock police believe Robert Mangan, 39, killed his four-year-old daughter Catherine and five-year-old son Joseph before he took his own life.
The bodies were found Sunday by Mangan’s wife, Linsday Mangan.
Officers were responding to the scene of what they believed was a possible suicide, but when they arrived, they discovered the two children were dead in a bed with their father, police said.
A cause of death wasn’t immediately released, but police said they were no obvious signs of trauma on the children.
All three bodies were taken to the medical examiner’s office for autopsies to determine causes of death, a police statement said.
Officer Steve Moore said the children’s mother found the bodies.

The deaths come amid a dramatic spike in homicides in Little Rock.
Following the Sunday deaths, Arkansas’ capital city has now seen 45 homicides this year, three more than all of last year.
A downtown Little Rock nightclub was the site of a shooting during a rap concert that left 28 people injured in early July.
The Little Rock Police Department began increasing officer patrols in certain parts of the city Friday in an effort to curb the violence.

Police spokesman Steve McClanahan told The Associated Press Monday that even with police working additional hours, situations like the apparent murder-suicide won’t be prevented.

‘You could have a thousand extra police, and you’ll still have this,’ McClanahan said.
Little Rock is on pace to approach an annual total of homicides not seen since the city’s gang wars of the early 1990s.
