Police in Port St. Lucie are investigating a domestic incident that resulted in three people being shot Monday morning, NBC affiliate WPTV reports.
The incident happened just before 8 a.m. in the 5000 block of Northwest Hann Drive.
Port St. Lucie police spokesman Sgt. Frank Sabol said the shooter, 32-year-old Aundra Allen, and his estranged wife, who just delivered the couple's baby four days ago, were involved in a domestic dispute.
Allen had been in Miami, where he lives, while his 27-year-old wife had been staying at her parents' house in Port St. Lucie.
Sabol said Allen drove to the home in St. Lucie County and encountered his mother-in-law, Sheron Thomas, in the driveway as she returned from taking the wife's 7-year-old child to school. Thomas confronted Allen, and he shot her multiple times.
Thomas ran to a neighbor's house for help. The neighbor then called police.
Police said Allen then entered the house and shot his wife in the back.
When police arrived, they found Allen behind the house with a self-inflicted gunshot wound to the head.
According to WPTV, both women were conscious when police arrived. Allen's condition is not immediately known, but is said to be significantly worse.
The estranged couple shares two children, a two-year-old girl and a four day old infant. The wife also has a 7-year-old child from a previous relationship.
Two small children, ages 2 and 4, were found inside the house. The children's aunt, who has also been staying at the parents' house, is taking care of the children.
