Thirty-seven-year-old Teerapol Pin-amorn, who allegedly shot dead his pregnant wife, her parents and two aunts and wounded two other relatives at their home in Uttaradit’s Pichai district on Sunday night, has been arrested in the border province of Ranong’s Kra Buri district, deputy national police spokesman Pol Colonel Krissana Pattanacharoen said on Tuesday.
The authorities also arrested four Thais who had allegedly helped Teerapol escape, Krissana added.
Following the 8pm report of a multiple homicide on Sunday, Uttaradit police rushed to the crime scenes – one a two-storey wooden house in Tambon Phayaman, the other a house 5 kilometres away.
In the first house they found the bodies of Kanokwan Intharasit, 53, and her sisters, twins Nampheung and Nampha Intharasit, aged 48.
In the garage of the other house were the bodies of Kanyarat Kingkaew, who was four months’ pregnant, and her father Wirat Kingkaew, 46.
All five victims had been shot with a 9mm pistol and police collected about a dozen spent cartridges at the two scenes.
Kanyarat’s allegedly jealous husband, Teerapol – caught on CCTV footage shooting dead Wirat and Kanyarat – was identified as the prime suspect.
Teerapol also reportedly shot and wounded two other male relatives at Wirat’s house, but they fled to safety towards an adjacent cornfield.
