A police officer in Texas has been formally charged following a tragic car crash that resulted in the deaths of two children and left several others injured. The officer, reportedly speeding to an emergency call without activating his lights or sirens, is now facing serious legal consequences.

Michael Hightower, a 28-year-old officer with the Baytown Police Department, has been indicted on two counts of manslaughter along with one count of aggravated assault. On Monday, Hightower surrendered himself to authorities and was subsequently released on a $150,000 bond.

According to official reports, on the evening of October 23, Hightower was responding to a call regarding “persons with a weapon,” during which a fellow officer had requested backup. As Hightower approached an intersection, he collided with a Honda Odyssey that was turning left, despite having a green light. The vehicle was occupied by a woman and five children.

The indictment highlights Hightower’s “high rate of speed” and his failure to use emergency lights or sirens. Local news outlet ABC affiliate KTRK reported, based on a police account, that although Hightower had the right of way with a green light, his excessive speed and failure to signal his emergency status made him culpable for the accident.

Following the crash, Hightower, along with two children, was airlifted to the hospital. Tragically, two young boys, Jude Russell, aged 10, and Ryver Russell, aged 8, succumbed to their injuries. The other three children, aged 16, 14, and 3, suffered severe injuries, including fractures and a brain bleed. A GoFundMe page has been set up to support the family. Officer Hightower underwent leg surgery and is currently on medical leave. He has been serving with the Baytown Police Department for over two years.

Baytown police said in a statement that Hightower is “cooperating fully with the legal process.”

“This tragedy leaves us without words,” Chief John Stringer said after the crash. “Our hearts are heavy with sorrow for everyone impacted. As a father I feel this loss deeply and my heart breaks for everyone involved. We extend our sincerest condolences to the family during this heartbreaking time.”

Hightower”s next court date is scheduled for Jan. 12.

Jude had a “beautiful and joyous spirit,” his obituary said.

“Jude loved memorizing random facts and would often pose profound questions that he expected answers for,” the obituary reads. “He was a boy whose body and mind were never still. Jude enjoyed fishing and playing and watching sports. Jude also had an affinity for harmless mischief and enjoyed pranks.”

Ryver had a infectious laugh and an electric personality, the obituary stated.

“Ryver had an uninhibited imagination that allowed him to create beautiful art and weave the most intricate stories. Ryver valued others and cared for those around him deeply. Ryver was witty and never shied away from making a sassy comment or comeback,” it said.
