Spurned boyfriend, 55, who gutted his ex-lover’s £400,000 home by dousing it with flammable liquid then setting it ablaze while she popped to the shops faces jail.The court heard Evans ‘couldn’t stay away’ from the home of Miss Paul, a manager for the charity Prama Care, and on January 9 he drove by in his works van.When he realised Miss Paul was not at home, he broke in using a crowbar and then wedged it over the front door so no one could get in.The court heard Evans took a number of drugs in an attempt to kill himself before starting the fire.Jane Rowley, prosecuting, said: ‘The fire started at about 1pm. Miss Paul would normally have been at home at that time, it was pure chance that day that she had gone out shopping nearby.’Evans made clear admissions. He said he couldn’t keep away. He drove past her mother’s address to see if her car was there.’It was so he drove in his works van with two, five-litre cans of acetone which he used to clean tools at work and broke into her home using a crowbar to force the door.’He set fire to newspapers before getting the large crowbar to wedge the front door shut to stop anybody else entering. The fire caught quickly and spread.’Evans went to lie down on a bed upstairs, hoping the fumes would overpower him and send him to sleep, but instead he got too hot, took off his shirt and opened the window.
