Jason Sinquefield would give anything to spend one more moment with his brother.

With his head bowed and Khalyl M. Wilson on his mind, that moment came — while he crouched over the spot where his brother was murdered Sunday night in an Orlando park.

“That’s my baby brother. That’s my blood baby brother. This ain’t no home boy, this ain’t no best friend. That’s my little brother," Sinquefield said.

Friends and family members stopped by Pleasant Valley Park all day Monday. Right now, there’s a small memorial growing for Wilson, who was well known in his neighborhood.

According to Orlando Police, the 18-year-old was shot outside the park near Ivey Lane at about 7:15 p.m. Sunday. It’s a place where Wilson and his friends from the neighborhood often played basketball.

“I love my grandbabies," said Jacqueline McCastler, Wilson's grandmother. "Whoever did this to my grandson, you may hide from man, but you won’t hide from God almighty, who I serve," she said.

McCastler was joined by Orlando City Commissioner Regina Hill. Hill said she checks on the park weekly because she got the city to invest close to $300,000 to revitalize the space for the neighborhood.

“It really is heartbreaking to think the very thing we wanted to do was reinvigorate this park and make it vibrant and make it a neighborhood park and someone was so reckless to come and take a life,” Hill said.

According to Orange County Public Schools, Wilson previously attended but was not currently enrolled at Jones High School. However, Sinquefield said his brother planned on going back to school Monday, the first day back from spring break.

“He didn’t drop out of Jones. He was going to school today. This was (supposed to be) his first day back," Sinquefield said.

“He said he wanted to get his grades together. He wanted to graduate. He just said on (Facebook) Live like three days ago. He wanted to graduate. He want to stop all the stuff he (was) doing," Sinquefield said.

Meanwhile, district leaders said grief counselors were at the school Monday, because so many students knew Wilson.

Detectives are following up with witnesses and processing evidence to identify a suspect in the slaying.

“I wasn’t here for my brother; that is what beats me up the most," Sinquefield said. “...I wasn’t here. That’s where I feel like I failed him at," he said.

Police have not released many details about a possible shooter but did say a black-type SUV may be involved. If you know who shot and killed Wilson, the 18-year-old's family members are asking you to call Crimeline at 1-800-423 TIPS.
