SPRING, Texas (KTRK) -- Harris County deputies are investigating the death of a 20-year-old woman, whose body was found lying in the middle of the street in Spring. She was shot once in the head, deputies said.Around 1:30 a.m., a call came in to 911 about a possible suicide in the Lexington Woods subdivision. But when deputies arrived to the 25000 block of Pepper Ridge Lane, they found Alyssa Reagins with a single gunshot wound to the head with no gun beside her.Steven Johnson says he called 911 after finding Reagins dead in front of his house. He says she was his daughter-in-law's friend, who had been staying with his family for the past two weeks."She was easy going," Johnson said.Johnson said around 12:20 a.m., Reagins got a call on her cell phone and started fighting with the person on the other end of the line. She went outside. An hour later, Johnson says he heard one shot and a car speed off."We found her laying in the street and my daughter-in-law started doing CPR on her, trying to revive her," Johnson said.Johnson said there were five adults staying in his house, including Reagins. Investigators say there were also five children, ages 4-11, living there."The kids were asleep," Johnson said.Investigators spent hours interviewing Johnson's family and neighbors."We're getting some conflicting stories so, at this point, we're not exactly sure what happened to her," said Sgt. Ben Beall with the Harris County Sheriff's Office.Deputies told Eyewitness News that they believe the shooting was a suicide, and someone took the gun before officers arrived."It's really scary," said Kellee Williams, who lives three houses down. "You don't really think it's going to happen in front of your house but apparently it does."
