( CNN ) -- A Florida man lit the mother of his 4-year-old son on fire early Monday , then chased her with a knife before she found refuge inside a convenience store , police said . Roosevelt Mondesir , 52 , was in jail Monday night after being charged with attempted first-degree murder , said Boynton Beach police spokeswoman Stephanie Slater . His alleged victim is at a Delray Beach hospital recovering from severe burns to much of her body and face . The woman is expected to survive her injuries , Slater said . Surveillance video shows the woman standing near a gas pump shortly before 3 a.m. Monday in her silver Mercedes Benz , as a man driving a white Jaguar -- later identified by authorities as Mondesir -- approaches . The two are at one point seen struggling . The woman tries to seek refuge inside the 7-Eleven , but is soon dragged back outside . The video later shows the woman running around on the pavement outside the store , the upper part of her body enveloped in flames . According to the report from the Boynton Beach Police Department , the woman -- interviewed about two hours later at Delray Medical Center , but not identified by police -- said she had gone to the 7-Eleven intending to meet her son 's father and son for a `` timesharing exchange . '' She and Mondesir do n't live together but they share custody of their 4-year-old child , the woman said . After realizing her son was n't in Mondesir 's car , the burning victim says she tried to get back in her vehicle . It was then that Mondesir came out with a red-colored can and began tossing gas on the woman and her vehicle , the woman told police . She ran , but after being pulled out of the 7-Eleven the first time , Mondesir `` threw fire onto her body '' and she `` became engulfed in flames , '' according to police . `` The victim began to put the fire out and remove her shirt , and then realized the ... defendant was also armed with a long ( possibly machete ) knife , '' police said . Officers arrived to find the woman `` with severe and fresh burns '' on her body and face , as well as pieces of her still burning shirt on the ground . Mondesir had run from the scene , leaving his Jaguar parked near the gas pumps . Boynton Beach police found him around 5:45 a.m. Monday in bushes near the 7-Eleven . After being treated himself at a local medical facility for burns , he is now in Palm Beach County 's main detention center , according to the sheriff 's office website . Sue Kohl , who lives across the street from Mondesir , describes him as friendly and helpful . Kohl said she was shocked to hear about the incident , which occurred about one-quarter mile from her and Mondesir 's homes . CNN 's Tom Watkins contributed to this report .
