TAMPA — He didn't have any enemies.
Sean Buchanan, 26, of Temple Terrace spent his time working two restaurant jobs, caring for his daughter and pursuing his dream of singing, said his mother, Mary Buchanan.
On Friday, his mother, father, brother, two sisters and aunt pleaded with the public to help identify Buchanan's killer.
"This was completely random as far as we know," said his father, Gary Buchanan, 63, of Tampa. "It's a tragic loss, not only for our family but for everyone who knew him."
Buchanan went to the movies at AMC Regency Theaters in Brandon and was found in his car down an embankment behind the theater hours later. An off-duty paramedic found him after 1 a.m. and called for help.
He had upper body trauma not consistent with a car accident, according to the Hillsborough County Sheriff's Office. Deputies are calling his death a murder.
Mary Buchanan, 58, said she went all over the world to find her children. Sean came to her from South Korea when he was 3 months old, she said.
"He loved to share his talents. He loved to sing," she recalled.
His sisters, twins Katie and Kelly Buchanan, 23, said their brother was an amazing person who lived for his 10-month-old daughter, SheaLynn Joon McMullen. "That was his joy," Katie Buchanan said.
Detectives are short on leads in the case. Buchanan had no criminal history and worked jobs at Chipotle and Chick-fil-A to support his daughter.
Only one man was seen walking toward the area where Buchanan's car was found at the time deputies believe he was attacked. Investigators released the grainy surveillance photo of a man in a baseball cap in the hopes someone will know him.
"He could be a witness," said Detective Larry McKinnon, a sheriff's spokesman.
