A former officer of the police killed at the least 24 kids and 11 adults.
In a knife and gun attack that started in a child care center in Thailand on Thursday.
In the footage from the scene, screaming family members can be seen crying outside the house.
The suspect was identified by authorities to be a former police officer.
He entered the child care center around lunch at the northernmost Thai city of Nongbua Lamphu.
After arriving home, he killed his wife and child and then himself, police said.
Police have said that he killed two children as well as nine adults outside the child care center including his wife and son.
Last month, a clerk shot co-workers at Thailand's Army War College in Bangkok, killing two and wounding another before he was arrested.
